Multicast - Bidirectional

Bidir PIM is designed for multicast apps that have a many to many architecture (as opposed to the typical one to many architecture of traditional multicast).

Configuring Bidir PIM is very similar to traditional PIM. To enable bidir-PIM on a router

Config#ip pim bidir-enable

And for the RPS just use the normal rp selection commands with the addition of the bidir option

STATIC RP: Ip pim rp-address {address} bidir
AUTO RP: Ip pim send-rp-announce (interface} scope {ttl} bidir
BOOTSTRAP RP: Ip pim rp-candidate {interface} bidiR

Use the same pim verification commands used for standard pim.
