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:
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: 184.108.40.206, 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: 220.127.116.11, RP: 192.168.1.50, next RP-reachable in 00:00:11
Group: 18.104.22.168, 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,
