7 Oct 2004 The RECEIVERS inform the routers what they want to receive. ? Internet Group Management Protocol (IGMP) - rfc2236 -> version. 2. The routers make sure the STREAMS make it to the correct receiving nets. ? Multicast Routing Protocols (PIM-SM/SSM). ? RPF (reverse path forwarding) – against source
PIM Sparse Mode (PIM-SM) is a multicast routing protocol designed on the assumption that recipients for any particular multicast group will be sparsely distributed throughout the network. In other words, it is assumed that most subnets in the network will not want any given multicast packet. In order to receive multicast data,
16 Oct 2008 PIM-SM takes an opposite approach. Initially, multicast traffic from a source isn't forwarded to group members. When a member somewhere in the network decides it wants to receive traffic for a group, it sends a join request to its nearest router. The join request is propagated up the multicast tree toward the
Understanding PIM Sparse Mode. A Protocol Independent Multicast (PIM) sparse-mode domain uses reverse-path forwarding (RPF) to create a path from a data source to the receiver requesting the data. When a receiver issues an explicit join request, an RPF check is triggered. A (*,G) PIM join message is sent toward the
24 Feb 2016 In this lesson you will learn about Multicast PIM sparse mode and how to configure it on Cisco IOS routers. R1#show ip mroute IP Multicast Routing Table Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected, L - Local, P - Pruned, R - RP-bit set, F - Register flag, T - SPT-bit set,
Dense-mode (DVMRP, MOSPF, PIM - DM); Sparse-mode (PIM - SM, CBT). 3. Multicast Forwarding. 4. Time To Live (TTL). Scope-limiting parameter for IP Multicast datagrams; Controls the number of hops that a IP Multicast packet is allowed to propagate; TTL = 1: local network multicast; TTL > 1: Multicast router(s) attached
8 Oct 2014 To get a better understanding of Multicast PIM-SM routing I created a case study. In the picture below the GNS3 topology I used. I used EIGRP between the routers for full unicast connectivity. On all te routers I configured "IP multicast-routing" and on the connected interfaces I configured the "ip pim
