I'm having a problem with Multicast RPs(Rendez-vous points)
We are enabling multicast in our network and run PIM-SM between a few routers. One router has to be the RP. We configured a Loopback interface and configured all the routers to that ip address:
interface Loopback0 description multicast rp ip address 192.168.1.50 255.255.255.255 ip pim sparse-mode ! ip pim rp-address 192.168.1.50 !
All the other routers show the RP as reachable:
client#sh ip pim rp Group: 22.214.171.124, RP: 192.168.1.50, uptime 02:09:17, expires never
But not on the router on which the above Lo0 is configured:
rtr#sh ip pim rp Group: 126.96.36.199, RP: 192.168.1.50, next RP-reachable in 00:00:11 Group: 188.8.131.52, RP: 192.168.1.50, next RP-reachable in 00:00:11
I don't understand why this router can't reach the RP. It is a local loopback interface, so it's always up and present in the routing table.
Does anyone have a clue?
Thanks & kind regards,
