Hello guys,
I had a question regarding implementing PIM-SM with BSR method chosen to elect the RP.
Attached is my network topology for reference. Router R1 and R2 will be configured with BSR priority 20 and 10, electing R1 as the BSR for our Multicast domain. R1 and R2 are also being configured as the RP for the network. All other routers in the network are configured for PIM-SM.
I was thinking of associating multicast groups 224.0.0.0/4 and 224.0.0.0/5 with R1 and associating multicast group 224.0.0.0/4 and 232.0.0.0/5 with R2.
With this being the case R1 would be specifically advertising for the following Multicast group:
224.0.0.0/4
224.0.0.0/5 (224.0.0.0-231.255.255.255.255)
While R2 would be specifically advertising for the following Multicast group:
224.0.0.0/4
232.0.0.0/5 (232.0.0.0-239.255.255.255.255)
This would also provide some form of load balancing where the 1st half of the Multicast range 224.0.0.0/4 is being specifically served by R1 and second half is being specifically served by R2. In the event router R1 were to fail, since R2 is still advertising the broad range of 224.0.0.0/4, R2 can take over the RP role in absence of R1 for the entire Multicast range.
Similarly, if R2 were to fail, since R1 is is still advertising the broad range of 224.0.0.0/4, R1 can take over the RP role in absence of R2 for the entire Multicast range.
Can somebody please suggest if the above makes sense? I look forward to hearing from you.
Regards,
B
