This is on a router configured as multicast RP. PIM Sparse mode and MSDP peering are used.
When I "sh ip pim rp" on the router, a couple of groups always have "RP-reachable in ..." displayed. Timer just cycles from 00:01:30 to 00:00:00.
Group: 224.0.1.39, RP: 10.132.0.9, next RP-reachable in 00:01:26
How to explain it? 10.132.0.9 is the RP address of the router.
Thanks
Gary
