Yes you can use multiple rp-address config commands but not for the same group as there is no way of proritizing which rp to use when there are multiple rp's for the same group.

Jon,


I just gave it a shot but no luck. Once I entered the new rp-address, the old one was no longer present in the run config.

You have to make sure the RP's are for different groups eg. from a 2621XM router


ip pim rp-address 192.168.6.10 2

ip pim rp-address 192.168.5.10 1

!

!

access-list 1 permit 239.10.10.10

access-list 2 permit 239.20.10.10

Thanks. This is going tough to accomplish because I have multiple mcast groups (see attached). And, I am looking to add 224.1.2.1 to 224.1.2.195 in addition to what is in the attached file.

Jon,


Here is what I did...


access-list 1 permit 239.0.0.0 0.255.255.255

access-list 1 permit 231.0.0.0 0.255.255.255

access-list 1 permit 235.0.0.0 0.255.255.255

access-list 1 permit 230.0.0.0 0.255.255.255

access-list 2 permit 224.1.2.0 0.0.0.255

ip pim rp-address 63.211.75.254 2

ip pim rp-address 10.33.63.1 1


I hope this will work.


Thanks,

Ws just about to post again to tell you that you can use wildcards but you seem have to worked that out yourself.


Let me know if it all works. Thanks for the rating.

Hi Jon,


It seems to be working at least for the old rp-address. I am no seeing mcast group from the new rp address. I am able to ping it but some troubleshooting commands are failing:


NJ00#sh ip rpf 63.211.75.254

RPF information for ? (63.211.75.254) failed, no route exists



NJ00#ping 63.211.75.254

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 63.211.75.254, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/9 ms

No, we actually want to get mcast (different groups) from different rp addresses.

Etienne,


The fact that the "sh ip rpf" fails but that the ping works is most probably due to the fact that the route to 63.211.75.254 is via an interface that is not configured for PIM.
