Jul 20, 2020 · Related- Multicast Address. 253 But I want for the multicast address 225. description multicast rp. ダイナミック. PIM (Protocol Independent Multicast) uses the unicast routing table to check In a shared tree, the root of the distribution tree is a router, not a host, and is located somewhere in the core of the network. Static RP, BSR RP, Embedded RP, oh My! IPv6 Multicasting. It is called “protocol independent” because it does not depend on a particular unicast routing protocol. 配置思路. 113. 3, start your multicast stream, check the ipmroute table on the local router to make sure there is a S,G entry, which will be <source ip>, <mcast group ip> Mar 1, 2019 · This shared root is called a Rendezvous Point (RP). 2. e. Feb 5, 2015 · Hi, I have already an RP for my system: ip pim rp-address 192. MSDP between P-RP (not C-RP) is not related to customer multicast streams. Apr 8, 2024 · RP Loopback ID - Specifies the loopback ID of the RP, if Is RP External is not enabled. The Firebox forwards the multicast traffic to the multicast group on the local network. R3 will now perform a RPF check for both multicast packets. 100/32 group 239. MAs uses 224. This traffic is forwarded to vlan 51 towards the VRF A located in a different VDC and sent to RP. PIM Accept RP is a security feature on Cisco IOS routers that prevents unwanted rendezvous points in the PIM sparse mode domain. There are two protocols we can use for this: Multicast Source Discovery Protocol (MSDP) PIM. When you have multiple RPs with the same IP address, it means that our sources and receivers will always be routed to the closest RP based on the unicast routing table. The RP extracts the native multicast packet and sends it to the RP tree towards the group members. そのため —The point at which routing to the specified multicast group or prefix switches from shared tree (sourced from the RP) to SPT distribution: 0 (switch on first data packet) (default)—The virtual router switches from shared tree to SPT for the group or prefix when the virtual router receives the first data packet for the group or prefix. You can also change the statement to accept what is in the auto-rp cache, and make certain that the access list (8 in this example) permits the necessary multicast group range. By default, a routing device running PIM is eligible to be the RP for all IPv4 or IPv6 groups (224. Here is a jump-start for all my CCIE candidate friends. Sending 1, 100-byte ICMP Echos to 239. The embedded RP feature that works for IPv6 multicast is a cool trick that embeds the IPv6 address of the RP within the IPv6 multicast group address. Protocol-Independent Multicast ( PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN, WAN or the Internet. Multicast traffic was flooded everywhere which allowed R6 to learn the source address. 255. Note: Sep 2, 2016 · Hi, I'm having a problem with Multicast RPs (Rendez-vous points) We are enabling multicast in our network and run PIM-SM between a few routers. Overlay Mcast Groups - Specifies the multicast group subnet for the specified RP. Dec 31, 2010 · Principle : The method used to provide RP redundancy for PIM Bidirectional is called phantom RP. For the PIM configuration, because we use Auto-RP, we have two choices: In general, the multicast mechanism is as follows: Receivers notify a central node (RP) of the address of the multicast group from which they want to receive traffic. Multicast traffic flows through the network until it reaches the last-hop (receivers) or AMT relays. Test case 1, consider we have 2 MVPN running in SPARSE mode, vpn1 and vpn2. ip access-list standard MULTICAST permit 239. Thus, all The RP receives these encapsulated data packets, decapsulates them, and forwards them onto the shared tree. There is only one shared tree (green) and all multicast operations are fully restored as soon as IGP has converged. 40 multicast groups but in addition, it also floods all multicast traffic May 2, 2024 · Configure MSDP Peering on all RPs in the Network. 15. For instance, to define boundary on interface it could be something like that: acccess-list 101 permit any 239. 因为在组播部署的时候，源注册过程组播源必须知道rp的路由，才能发送过去，源注册报文是单播报文。 另外组播分发树建立的过程中，是需要查到组播源（或者rp）的路由的，在组播中我们称为rpf检查，这个也需要单播路由的支持。 Dec 15, 2010 · The RP not accepting the Register messages from you (check the source address of the Register stream!) The RP not knowing the backward route either to you or to the source of the stream (again, be careful about the souce of the Register packets) Problem in propagating the PIM Join message from the RP towards the source of the multicast stream El RP no es más que una referencia en la red, y actúa como un vector de encaminamiento (Routing Vector - RV) apuntando hacia el lugar de la red donde el tráfico multicast converge. Jul 18, 2016 · ip pim rp-address 10. This means that the receivers really don’t care what source they receive multicast traffic from, all sources are accepted. We can verify that it’s running: Internet address is 192. Jun 2, 2016 · In different documents the examples for configuring multicast boundary (and the range of group addresses advertised by RPs) are showing at least two ways of applying ACLs. interface type number. As noted above, IGMP is enabled on eth1/4 which connects to the receiver. 39 and 224. Sending traffic from one (or multiple) sources to a group of receivers is called multicast. The RP model shifts the burden of finding sources of multicast content from each router—the (S,G) notation—to the network—the (*,G) notation knows only the RP. 0/4 range (the entire class D range), but if we want, we can configure our router to allow only PIM join/prune messages toward the groups that we want. Example: priority of 100 is higher than priority of 101. 255 MULTICAST. Jul 30, 2017 · For source, enter multicast addresses 224. Generally, static RPs are backups for dynamic RPs to enhance the robustness and operational manageability on a multicast network. In the primary sparse mode multicast routing protocol, Protocol Independent Multicast sparse mode (PIM SM), the core router at the root of the shared tree is the rendezvous point (RP). The first 4 bits in the first octet are 1110 in binary, meaning we have the 224. We need something that can synchronize information between RPs. Step 4. 40. RP design considerations overview . I am using multicast hammer to make the tests, this is not in production yet (because of me). 0/24 that points to R1. You configure a router network to support multicast applications with a related family of protocols. The multicast address is used for transporting multicast traffic in the fabric underlay. Dưới đây là 2 cách sử dụng chính của Multicast mà bạn thường thấy: 1. AMT Relay is a multicast router configured to support transit routing between nonmulticast capable internetwork and the native multicast infrastructure. 224. The root of the RP tree is the Rendezvous Point. BSR however, is a standard and included in PIMv2, unlike AutoRP which is a Cisco proprietary protocol. By default, multicast routing is disabled, and there is no default mode setting. 255 range for IP multicast addresses. Aug 24, 2022 · An attack target needs to be explicitly “joined” to the multicast stream. In this example I want to show you how to configure IPv6 multicast using BSR. set srcintf internal1. Multicast Source Discovery Protocol (MSDP) is the key protocol that makes Anycast RP possible. Therefore, both these commands need to be put on both Nexus boxes. For redundancy purposes, more than one RP may be configured to improve the availability of the multicast solution. そして、特定のマルチキャストグループのRP Nov 10, 2020 · The RP is a router, somewhere in the network, that knows how to reach the multicast source device. 3. Regardless of the source address, multicast forwarding is according to the multicast group address to which the packets are addressed. To configure the device as a node in a RP kemudian mulai meneruskan grup di sepanjang jalur itu, dan akhirnya perangkat yang membuat permintaan menggunakan IGMP mulai menerima grup multicast juga. 1 to 225. 168. Example: Multicast has many advantages. Modes of Operation: PIM Dense Mode; PIM Sparse Mode; PIM Dense Mode: Doesn’t use RP. The Candidate RPs send this data to 224. SW-RED-ISO10# The mapping agent sends RP-to-group mapping information to all PIM routers over the Cisco-RP Discovery multicast address 224. EL RP puede configurarse como una dirección no asignada a ningún dispositivo en particular, denominado Phantom RP. 41. Because the multicast routing protocol is PIM-SM, we need an RP, which is the R3 loopback IP address, 1. As a result, a shared tree is sometimes referred to as an RP Tree (RPT). By doing this, multicast-enabled routers can extract the RP address just by looking at the multicast group address and using it for a shared tree. In PIM-SM mode, the central point in the multicast domain is the Rendezvous Point (RP). ip address 192. When sending these messages, the candidate RP acts like a regular multicast source. Hosts that send multicast packets are registered with the RP by the first hop router of that host. Segera setelah paket multicast pertama dari RP tiba di router "hop pertama", yang menerima permintaan bergabung IGMP asli dari perangkat penerima, router hop pertama itu memiliki informasi Nov 28, 2023 · When troubleshoot, the ping command is the easiest way to generate multicast traffic in the lab to test the multicast tree because it pings all members of the group, and all members respond. 10. The most notable feature of PIM-SM is that multicast is distributed from so called Rendezvous Points (RP). When no RP is known, the packet is flooded in a dense-mode fashion. Apr 23, 2009 · Hosts that send multicast packets are registered with the RP by the first hop router of that host. May 10, 2009 · PIM-SM Static RP의 기본동작에 대해서 알아보기로 합니다. Link local traffic is never forwarded. It appears that NAT is working for standard traffic, but it looks like it is not translating the source address of the multicast traffic: we're translating 10. Smaller non-negative value is considered of higher priority. Cisco Nexus switches can use anycast RP without MSDP. Dec 8, 2023 · class-map type multicast-flows name. The RP tree is a distribution network that all sources share to deliver multicast data. The idea behind anycast RP is that we configure a single IP address on multiple routers and advertise it in our IGP. In this example, Static RP is selected. In this example, RP-1 and RP-2 are both configured as peers: RP-1: feature msdp. We recommend configuring a sink RP for all possible multicast groups in your network, because it is possible for an unknown or unexpected source to become active. The RP is notified of the location of the data source (multicast source) and the address of the multicast group to which the multicast source is to send traffic. Each RP handles distribution of one or more multicast groups, pimd can be configured to advertise itself as a candidate RP rp-candidate, and request to be static RP rp-address for one or more multicast groups. The following example filters PIM join and prune messages for group addresses 224. Sending traffic from one source to a single destination is called unicast. Prior to 1. One of the disadvantages is that we require applications that support multicast and we have to configure the network to support it. IPv6 Multicast BSR and RP Example. end. RP-announce messages arrive, the mapp ing agent selects the router or sw itch with the highest IP address as the active RP and stores this RP address in the Group-to-RP mapping cache. 配置基于PIM的Anycast RP，可以缓解单个RP的压力，并实现主机的就近加入。 配置各 交换机 的接口IP地址和单播路由，实现网络层互通。 Sep 27, 2022 · Nhưng vì Multicast là gói một chiều nên bất kỳ phản hồi nào cũng cần được thực hiện bằng một giao thức riêng biệt. Eliminating Multicast Encapsulation (Phase 2) Data encapsulation, while initially required before the multicast path is established, is inefficient because it requires the transmission of data that is extraneous to multicast. The Nov 15, 2019 · The RP is on a globally routable segment in another location. 255 range has been reserved by IANA to use for network protocols. Multicast for IPv6 can be configured using static RPs, BSR or embedded RP. 1 192. We configured a Loopback interface and configured all the routers to that ip address: interface Loopback0. To solve this issue, PIM sparse mode uses a RP (Rendezvous Point) in the network. If the multicast traffic from a specific source is sufficient, the first hop router of the host may send Join messages toward PIM is used for efficient routing to multicast groups that might span wide-area and interdomain internetworks. Aug 1, 2016 · The multicast source sends traffic to the first-hop. 0 – 224. In this diagram, a server sends multicast traffic through a router and the Firebox. 39:496 to send its information to MAs. The source, 192. ] 4) Configure the multicast group join on internal1: conf vdom. 우선 중요한 용어 하나를 확인하고 자 Dec 26, 2010 · With Anycast RP, RP failover depends only on IGP convergence RP convergence = IGP convergence In our example, if RP1 fails, there is only one route left for the RP address pointing to RP2 and so all routers use RP2 as RP. Currently, used version of PIM is version 2. ip msdp originator-id loopback1. Example: Device(config-if)# class-map type multicast-flows proxymap: Configures the interface with a class-map where the uplink interfaces for different multicast groups are defined. . The MRIB is built using PIM and the routing table. 2 12 override. The argument for BSR is that you don't need to enter any commands on the routers to receive the RP and that you could easily change the RP without adding any commands to the routers. To use multicast, you must understand the basic components of a multicast network and their relationships, and then configure the device to act as a node in the network. It finds an OSPF entry for 192. There are various multicast routing protocols that can run between the routers to form either a source or shared tree. あらためて、RPについて振り返ります。. Rendezvous point can be, as stated above, configured statically for a multicast group range by configuring the RP address on every router included in the multicast domain. Phân phối luồng dữ liệu AV. 26. A rendezvous point (RP) is a role that a device performs when operating in Protocol Independent Multicast (PIM) Sparse Mode (SM). However, if the default MDT group is configured in a PIM Source Specific Multicast (PIM-SSM) environment rather than a PIM-SM environment, the receiver PE needs information about the source Dec 8, 2023 · The RP keeps track of multicast groups, and the sources that send multicast packets are registered with the RP by the first-hop router of the source. Mar 17, 2016 · When hosts join a multicast group, the directly connected routers send PIM Join messages toward the RP. 16. 2 and 225. It is simple to configure a static RP, and it can be done with a couple of configurations on each router. MBGP can indicate whether an advertised prefix is to be used for unicast routing, multicast RPF checks or both. For BGP to support IPv6 or multicast, BGP is extended. 0/4 or FF70::/12 to FFF0::/12). 4. 250/32 // Above line is for any SRC and specific group ! if several RPs are available for multicast group, and they are both with same scope, then RP with highest priority is chosen. Sending traffic from one source to everyone in the subnet is called a broadcast. To filter PIM sparse mode join and prune messages at the egress interfaces, create a policy rejecting the group address, source address, outgoing interface, or PIM neighbor, and then apply the policy. PIM messages will be exchanged between spine switches so all spine switches know about the multicast sources. This to limit the RP only to the multicast group: 234. 4 8. The scope of this document is to explain the basic concept of MSDP and the theory behind Mar 24, 2010 · 24 March 10. user@host# set priority 5. When there is only one router per segment that forwards multicast traffic, there will be no loops. Mar 8, 2019 · How do you specify the multicast PIM RP-address when the intended RP is a pair of router's running HSRP? I have tried using the commands documented in 'HSRP aware PIM' on the router interfaces, and declaring the RP using the standby (vip) address. The process starts when a receiver requests multicast data from a group (G). The RP keeps track of multicast groups. the IP address advertised as RP address is not defined on any routers. The range of the multicast groups is from group 225. 81a different RP So I have added ip access-list standard grpmulticast permit 225. both these information has to be distributed over PIM DM to avoid Shared Tree – A shared tree is a multicast distribution tree in which the root is the Rendezvous Point (RP), rather than the source. For multicast routing, we care about where the source is located. RP type is 'None' as this will manually configure the remote RP as shown below with the groups allowed. The main advantage is the scalability compared to unicast traffic. Mar 8, 2019 · 09-01-201611:12 PM - edited ‎03-08-201907:16 AM. Some of the addresses are reserved, however, and we can’t use them for our own applications. 2 8. Đầu tiên là phân phối các luồng dữ liệu âm thanh Jan 22, 2016 · With anycast RP you will need MSDP of course so that all RP's knows of all the sources. It is termed protocol-independent because PIM does not include its own topology discovery mechanism Anycast RPの目的. Sep 25, 2018 · The receiver config is similar to the sender, the difference being IGMP enabled on the client facing interface to ensure the clients join the multicast group. 1. 3, it was mandatory to have the RP inside the fabric. To this: ip pim accept-rp 10. [also considering conf global\tp-mc-skip-policy, which will skip firewall policies for multicast traffic. I was doing a small OSPF Lab in GNS3 with three routers in a single broadcast domain R1 (Router id 1. It sees the source address is 192. ip pim anycast-rp 10. 3 the SD-Access fabric supports an external RP. Starting from 1. 1/24. 3 ! ip pim rp-address 2. One router has to be the RP. 1, timeout is 2 seconds: Feb 27, 2019 · Multicast sent to fex on vlan 50 (vpc vlan), in this case , both Switch A and Switch B have OIF for VRF B as the source is directly connected to it and it is in vpc vlan. Readers digest version: “Auto-RP is out, Dense-mode is out, IGMP is replaced with Multicast Listener Discovery (MLD). 1 )is Drother, R2 (2. interface ethernet0/0. We can do that with Bidir since there is no packet unicasted to the RP address; the RP is just the root of the shared tree, i When configuring Auto-RP you first configure the candidate RPs to tell the mapping agent they exist. PIM-SMにおけるRPの設定方法は次の2通りあります。. The DF will be elected using the following mechanism: The router with the lowest metric to the RP will be the DF. BSR uses two roles: Jan 15, 2019 · Configuration. As a PIM join travels up the tree, routers along the path set up the multicast forwarding state so that the requested multicast traffic is forwarded back down the tree. hi, Mapping Agent (or Management Agent) is used to multicast RP address to all PIM SM routers, Auto-RP uses 224. It sends the multicast traffic out all of its interfaces by default. In the PIM-SM model, only network segments with active receivers that have explicitly requested multicast data will be forwarded the traffic. 3) configure the firewall policy that allows the traffic. 6 and will send the updates to others on Multicast RPF (Reverse Path Forwarding) One of the key differences between unicast and multicast is that for unicast routing, we only care about where the destination is located and how to get there. The RP then sends Join messages toward the source. Anycast RP is a redundancy and load balancing mechanism applicable to R3 is a client (receiver) of MC groups and all that we need for receiving multicast on R3 it is just sending IGMP report (join) toward the R2 (we can forget about PIM), and R2 knows where RP is. For a large-scaled PIM network, configuring static RPs is a tedious job. This isn’t always practical. There are two main RP redundancy mechanisms applicable to the ASM multicast distribution model: Anycast RP and Phantom RP. First, we need to configure PIM on the interfaces between the four switches, on the interface where is source is located (VLAN10 of SW-1), the interface of the clients or receivers (in this case, the loopback0 of SW-4) and on the RP interface (loopback0 of SW-3). Here is relevant config. In a shared tree, the root of the distribution tree is a router, not a host, and is located somewhere in the core of the network. The 224. Anycast RPの目的は、PIM-SMにおいてRPの冗長化と負荷分散を実現することです。. In the next lessons, we’ll closely examine IGMP, PIM, and how to configure multicast. 0. These lessons explain the different protocols we require to make multicast work on our routers and Mar 28, 2023 · The remote PE, which acts as a receiver for the MDT multicast group, then sends (*, G) joins toward the RP and joins the distribution tree for that group. If the multicast traffic from a specific source is sufficient, the receiver’s first-hop router might send join messages toward the source to build a source-based distribution tree. Jul 25, 2018 · I have to be able to receive and originate multicast traffic from some vlans on the red domain to a device on WAN_1. Therefore, attacks on a router with multicast packets can only originate from directly attached attackers. Sep 18, 2020 · Multicast forwarding on SD-Access fabric uses two methods for distributing the traffic on the underlay: Head-end Replication and Native Multicast. 2) is BDR and R3 (3. 81 ip pim rp-address 172. For Auto-RP configuration, check the boxes for “Forward Auto-RP updates” and “Listen to Auto-RP Updates” on the “Rendezvous Points” page. IPv6 multicast routing is a fun topic, and is often either loved or avoided :). By default, an RP will accept all multicast groups in the 224. Multicast PIM Bootstrap (BSR) BSR (Bootstrap) is similar to Cisco’s AutoRP, it’s a protocol that we use to automatically find the RP (Rendezvous Point) in our multicast network. Junos OS supports bidirectional mode, sparse mode, dense mode, and sparse-dense mode. (Optional) For source-wildcard , enter the wildcard bits in dotted decimal notation to be applied to the source. Dec 18, 2020 · Explanation: The multicast routing information base (MRIB) is a topology table that is also known as the multicast route table (mroute). This limits how many router hops away the information will still be valid. The RP is a router that receives multicast traffic destined for the multicast group. 0 through 239. 40 in MULTICAST_FILTER acl is “ R3 acts as PIM-DR ” Sep 28, 2011 · conf firewall multicast-policy. It contains the source S, group G, incoming interfaces (IIF), outgoing interfaces (OIFs), and RPF neighbor information for each multicast route as well as Mar 1, 2019 · MBGP is an extension of BGP that can carry routing information for multiple network layer protocols. In the example, a single RP is defined for all possible multicast data streams. The receiver's DR sends a PIM (*,G) Join message toward the multicast group's RP. Sep 15, 2021 · ip pim rp-address 192. The ip pim autorp listener command floods auto RP 224. When you configure Network Address Translation (NAT) on a Cisco IOS® router, multicast sources and receivers, or Protocol Independent Multicast (PIM) entities, such as Rendezvous Points (RPs) or RP mapping agents, work on either side of the NAT router without additional configuration commands. 50 255. This VDC has vlan 11 in VRF A and vlan 51 in default VRF. External RP. Current IGMP host version is 2. The Time-To-Live (TTL) value is set in these messages to limit the scope of the mapping. R1 will be the receiver of the multicast stream, R2 will be the BSR and R3 will be the RP. Jun 1, 2001 · Anycast RP allows two or more rendezvous points (RPs) to share the load for source registration and the ability to act as hot backup routers for each other. 50 grpmulticast override ip mroute 82. Using sparse mode, our receivers require the RP Protocol Independent Multicast. As the name lets suppose, we use a virtual RP, i. Nov 7, 2012 · The commands for both Nexuses for the setup are: ip pim anycast-rp 10. edit 1. Type escape sequence to abort. Wan router is acting as RP for all of them. The packet that it receives from R1 will pass the RPF check since we receive it on the Fa0/0 interface, the one it receives from R2 doesn’t. Here’s how it works: Each router that receives multicast traffic from a source will forward it to the RP. Protocols Used When Configuring the Multicast Networks: 1) PIM (PROTOCOL INDEPENDENT MULTICAST): Used for Router to Router signalling. Exactly how the RP finds the unicast IP address of the source varies, but there must be some method to determine the proper source for multicast content for a particular group. In this example, the RP IP is set statically on all the routers. An RP is required only in networks running PIM SM. ip pim accept-rp 10. 0 255. The packets then follow the (*,G) multicast tree state in the routers on the RP Tree, being replicated wherever the RP Tree branches, and eventually reaching all the receivers for that multicast group. IGMP is enabled on interface. スタティック. Mar 30, 2011 · at this point the only way to receive the needed multicast packets is to add in the routing table a rule to reach the network where the sender is (another network) trough the dvb, as if the dvb needs to reply to the multicast sender; let say a sort of source sender multicast mode. These extensions are called Multiprotocol BGP (MP-BGP) extensions. Apr 9, 2012 · Assuming your query is why you need MSDP on Provider multicast n/w, As mentioned earlier, if you have Inter domain scenario or Anycast RP, you need MSDP to communicate the active source between RP. 40 multicast groups on sparse mode interfaces, allowing all routers to receive the group-to-RP mapping information. PIM sparse-dense mode also allows us to flood the auto RP 224. Mapping agents periodically multicast the contents of their Group-to-RP mapping cache. Now what i know is DR will lisen to Multicast IP 224. 255 Multicast Configuration Overview. In my experience you would rarely change the RP and preferably your changes Enterprise customers typically use Anycast RP for configuring a Protocol Independent Multicast sparse mode (PIM-SM) network to meet fault tolerance requirements within a single multicast domain. 0 0. 100, sending to the multicast group 224. Click "+" to add the RP. This is an example: ip pim accept-rp auto-rp access-list 8 permit 224. 07-14-2013 12:07 AM - edited ‎03-04-2019 08:27 PM. 3) is DR. 0 in this case. PIM-SMにおいて、マルチキャストグループごとにRPアドレスが必ず必要です。. Hours of labing I understood, the main reason why we need acl with 224. This designated forwarder is the only router on the segment that is allowed to send multicast traffic toward the RP. In anycast RP, two or more RPs are configured with the same IP address on loopback interfaces. 5. Underlay Mcast Address - Specifies the multicast address associated with the VRF. Configure the groups for which the routing device is the RP. 1 route-map filter-registration ! Route-map filter-registration deny 5 match ip multicast source 172. 40, which carry Auto-RP information. Posted by INE. Here, you can see two important points: First, I use an ACL to be the more specific possible. address (IP address) at what address you have to look for RP for multicast group specified in group field. Dec 7, 2021 · Configuring a sink RP does not interfere with Auto-RP operation because, by default, Auto-RP messages supersede static RP configurations. 100 and checks the unicast routing table. Jul 14, 2013 · OSPF Multicast address. set dstintf internal2. Jan 15, 2019 · Now, we must configure multicast-routing and the static RP, on the four switches: SW-1,2,3,4: ip multicast-routing ! access-list 12 permit 234. La dirección del RP no tiene por qué estar First, we have to enable multicast routing and PIM on the interface otherwise, the router won’t process IGMP traffic. 250/32 // Above line is specific to SRC/GROUP pair Route-map filter-registration deny 7 match ip multicast group 239. 100, is connected on R4 Ethernet0/0. Source Specific Multicast (SSM) The multicast that you are probably familiar with (PIM sparse and dense mode) using IGMPv2 is also known as ASM (Any Source Multicast). Each Nexus switch that is a member of the Anycast RP set must be configured to peer with all other Nexus switches. The following example limits the groups for which this routing device can be the RP. All interfaces between devices are in pim sparse-mode. However, only one RP can forward multicast traffic for a multicast group at a time. 0 to 10. At this point, packets are forwarded on a shared distribution tree. Traffic flows from the source to the receivers through the RP, with a source tree from the source to the RP, and a shared tree from the RP to the receivers. In most cases (Auto-RP is the main exception), routers only listen to and receive “link local” multicast traffic. ix bz zb wl ru kt mm fw ag ux
