BIDIR-PIM
In bidirectional PIM, multicast groups are carried across the network over bidirectional shared trees. This type of tree minimizes the amount of PIM routing state information that must be maintained, which is especially important in networks with numerous and dispersed senders and receivers. It is a special extension to the PIM SM concept that uses only the shared tree for multicast distribution.
ip pim rp-address 2.2.2.2
R5(config)#int f0/0
R5(config-if)#ip igmp join-group 224.10.10.10
Configuring bidir on all routers
ip pim bidir-enable
ip pim rp-address 2.2.2.2 bidir
