I am configuring ipv6 multicast in the below-shown setup. ospfv3 and PIM sparse-mode is enabled on all the routers and on all the interfaces of the router.
R3 is the RP. R6 joins FF08::1 multicast group and mroute entries are created from R6->R1->R2->R3.
If the outgoing interface is gi0/1(interface pointing to R2) then ping works from R3.
R3#ping FF08::1 source lo0Output Interface: Gigabitethernet0/1======>Gigabitethernet0/1 points to R2

But If I ping from router R3 but give the output interface Gigabitethernet0/0(pointing to R4) then ping does not work. Why?
R3#ping FF08::1 source lo0Output Interface: Gigabitethernet0/0
Request 0 timed out
Below is the configuration of all the routers.
Hi @sachin30720041 ,
You need to configure the RP address on all devices using the following command, including on the RP itself.
ipv6 pim rp-address <RP ipv6 loopback interface address>
