Hi, If you have control over the TTL of the multicast packets, you can make use of the TTL threshold interface command (ip multicast ttl-threshold). For instance, set a threshold of 15 on Serial0/3. Multicast packets with a TTL lower than 15, will not be forwarded out that interface. Now ensure that packets that DO need to be forwarded out that interface, have a TTL of more than 15 when they arrive at your router.

Serial0/2 is sending the multicast to Ethernet0/0 and Serial0/3. How can I block the multicast traffic sending to Serial0/3 and only send to Ethernet0/0. I cannot tun off the "ip pim dense-mode" command because there is another multicast traffic sending from Serial0/3 to Ethernet0/0. Any Hints.
