I have a 6509, SUP 720. Latest IOS.
Two VLANS: 10 and 20.
10.10.10.254 is the vlan 10 interface.
192.168.1.254 is the vlan 20 interface.
I have a user shooting multicast with a TTL of 1 into vlan 10. Unfortunately the TTL is hardcoded into this custom application and is unchangeable.
I need a way of routing this traffic into VLAN20 via IGMP/MC routing. There is the possibility that there will be future routers/switches hanging off of vlan 20 whom may have users who want this multicast.
I've read Google'd like crazy and read Cisco's docs on multicast regarding thresholds, IGMP snooping etc..I've experimented but to no avail. I tried an "ip igmp join ..." on vlan 20, it joins but my hosts still cannot IGMP request the stream.
Am I up the creek without a paddle?
thanks for any help,
