If we connect hosts to eth0/0 of R1 and eth0/0 of R2 with IP address in the same subnet, they can ping to each other. That means frames arriving on eth0/0 of R1 are encapsulated by L2TPv3 protocol and then are decapsulated on Eth0/0 of R2.
But when host generates the multicast-traffic, then multicastframes or packets are not getting encapsulated by L2TPV3 protocol as those are not received on the other end of the virtual tunnel.
Host1 can Ping host2 ( from 10.1.1.1 /24 to 10.1.1.2 /24 ).
We replaced the hosts by routers and enabled OSPF on the corresponding interfaces on the routers, OSPF nbr relationship was not coming up. Debugging shows that it is sending the multicast hello packet but it is not receiving the corresponding hello packet from other router.
Multicasting frames are getting encapsulated.
Please share the experience. Thanks in advance Subodh
I have tried your configuration and for me it's working. I have configured OSPF on the edge routers and it's working without any issue. Below you have parts of the config that are related to this troubleshooting.
My topology is R3(edge)F0/0 <-> Fa0/0 R1 S0/0<-> S0/0 R2 Fa0/0 <->Fa0/0 R4(edge)
R3 Fa0/0 10.10.34.3 /24
R4 Fa0/0 10.10.34.4 /24
On S0/0 interfaces of R1 and R2 I have a point-to-point connection and Loopback (R1 - 10.0.3.201, R2 - 10.0.3.202) addresses of R1 and R2 are routed over L3 link to have reachability:
## R1 ##
