Configuring Bidirectional PIM
Problem
You want to use Bidirectional PIM to improve efficiency of your sparse-mode multicast network.
Solution
To use Bidirectional PIM, you must configure all of the routers in your network to support this method of building multicast forwarding trees. The RP configuration looks like this:
Router-RP1#configure terminalEnter configuration commands, one per line. End with CNTL/Z. Router-RP1(config)#ip multicast-routingRouter-RP1(config)#ip pim bidir-enableRouter-RP1(config)#ip pim rp-address192.168.12.1bidirRouter-RP1(config)#ip pim rp-candidateLoopback0group-list 15 bidirRouter-RP1(config)#ip pim bsr-candidateRouter-RP1(config)#Loopback0 1access-list15permitRouter-RP1(config)#239.5.5.0 0.0.0.255access-list15deny anyRouter-RP1(config)#interface Loopback0Router-RP1(config-if)#ip addressRouter-RP1(config-if)#192.168.12.1 255.255.255.255ip pim sparse-modeRouter-RP1(config-if)#exitRouter-RP1(config)#interfaceRouter-RP1(config-if)#FastEthernet0/0ip addressRouter-RP1(config-if)#192.168.1.1 255.255.255.0ip pim sparse-modeRouter-RP1(config-if)#exitRouter-RP1(config)#interfaceRouter-RP1(config-if)#Serial1/0ip addressRouter-RP1(config-if)#192.168.2.5 255.255.255.252ip pim sparse-modeRouter-RP1(config-if)#exitRouter-RP1(config)#endRouter-RP1#
And the other multicast routers in this network will be configured to use Bidirectional PIM for this RP, as follows:
Router1#configure terminal Enter configuration commands, one per line. ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
