Hi All,
This is regarding the syslog messgae which we are reciveing in our core routers.
Evere 2 or 3 days, we are receviing this below message in our core routers, it looks like we are loosing the pim neigbour ship.
But the users are not complaing, the interfface which is connectd to this core intreface are multicast source router.
When we check the interface, I dont see any drops. This issue is recently started. The other end routers are 6513.
Our core routers are 7609 with RSP. We are using SSM for multicast. ISIS is the IGP protocol.
below is the logs. We are getting this message only from this interface, not from other connected routers.
Any help would be
