Hi team,
In one of my Lab, i am unable to ping a multicast group from one of my spoke
router R5. My upstream router R3 is able to ping it though. I am connected
on a p-2mp FR network. my Hub router R3 is able to ping the group address.
Switch connected to hub router is the MA. RP is the R1 router connected to
the switch.
R1 is the primary RP and R3 is the back RP for the same groups.
What could be the reason. I have unicast connectivity to the router who has
joined the groups 224.2.2.2, 224.3.3.3.
Here is the "show ip pim rp mapp" from R5
R5#sh ip pim rp mapp
