626 Bidirectional Forwarding Detection
Chapter 31 PIM Sparse Mode PIM Sparse Mode is supported only on platforms: c e PIM-Sparse Mode (PIM-SM) is a multicast protocol that forwards multicast traffic to a subnet only upon request using a PIM Join message; this behavior is the opposite of PIM-Dense Mode, which forwards multicast traffic to all subnets until a request to stop. Implementation Information • The Force10 implementation of PIM-SM is based on the IETF Internet Draft draft-ietf-pim-sm-v2-new-05. • The SPT-Threshold is zero, which means that the last-hop designated router (DR) joins the shortest path tree (SPT) to the source upon receiving the first multicast packet. • FTOS reduces the number of control messages sent between multicast routers by bundling Join and Prune requests in the same message. • PIM-SM on VLAN interfaces is supported on TeraScale platforms only. Protocol Overview PIM-SM initally uses unidirectional shared trees to forward multicast traffic; that is, all multicast traffic must flow only from the Rendezvous Point (RP) to the receivers. Once a receiver receives traffic from the RP, PM-SM switches to shortest path trees (SPT) to forward multicast traffic. Every multicast group has an RP and a unidirectional shared tree (group-specific shared tree). Requesting Multicast Traffic A host requesting multicast traffic for a particular group sends an IGMP Join message to its gateway router. The gateway router is then responsible for joining the shared tree to the RP (RPT) so that the host can receive the requested traffic. 1. Upon receiving an IGMP Join message, the receiver gateway router (last-hop DR) creates a (*,G) entry in its multicast routing table for the requested group. The interface on which the join message was received becomes the outgoing interface associated with the (*,G) entry. 2. The last-hop DR sends a PIM Join message to the RP. All routers along the way, including the RP, create an (*,G) entry in their multicast routing table, and the interface on which the message was received becomes the outgoing interface associated with the (*,G) entry. This process constructs an RPT branch to the RP. FTOS Configuration Guide, version 7.7.1.0 627
