Multicast Setup

This should have been straight forward, but.... Here's the hardware:

6509 (native mode IOS) ---- 4006 (CatOS) --- 3620 --- PC via crossover cable

The 6509 has other 6509's & 4006's hanging off of it with the WAN routers tied to those. Mutlicast traffic is running throughout the network and is seen on the PCs connected to the 4006 that the 3620 is connected to. Here's the config on the 3620 (the PC is connected to FA1/0) and the "show ip mroute 239.192.1.101" for a test stream:

ip multicast-routing

Outgoing interface list: Null

When I connect the PC to the 4006 that the 3620 is connected to, I get the stream. But, I can't get it across the 3620. Any suggestions?

Re: Multicast Setup

Hi,

Try removing the TTL threshold configuration on the Fa1/0 interface.

Revert back with results..

Re: Multicast Setup

Shoot... that was too easy... can't believe I missed that. It works now! Thanks!
