I have configured multicast between two sites running two Cisco 2600 router over T1 and Cisco 2948 switches behind them. I'm runing weblogic multicast with the TTL of 2 or higher. I see multicast on one end but the other end shows nothing.
My interface config look like this
interface FastEthernet0/0.3
encapsulation dot1Q 103
ip address 192.168.216.1 255.255.255.128
ip pim sparse-dense-mode
no ip route-cache
no ip mroute-cache
My other end is .129/25 and I have cgmp enabled on Cisco 2948.
Is there anything I'm missing in the configuration? Please advice.
Solved! Go to Solution.

Silly question but have you configured PIM on the serail link between the two sites?

It is hard to comment with so little info. Did you configure a static RP or auto-RP? Can you attach the output of a show ip mroute" from the router ar the site that doesn't receive the multicast packets.

Not a silly question because this is something I missed. It now works when enabled on serial interface. Thanks a lot
