All things related to multicast

Thanks Hans & Lucy.

I got the Talarian shim.  Diddled the registry entry to use the old
v3lite port 659 since I think my IOS doesn't support the IANA-assigned
port yet.  Still no luck.  My source is on Vlan39, client on Vlan7,
both on the same router.  Source is running Win2K with the Talarian
shim. Client is WinXP.  IOS version is related to 12.1(8a)E.  Once
finals are over we'll be going up to the next supported release.

On the source and client vlans I am seeing these similar messages when I
debug ip igmp:

I'm concerned about "0 sources" and "ignored" :-)

Here's a snippet from my router config:

ip pim ssm default 
...
interface Vlan7
 ...
 ip pim sparse-dense-mode
 ip igmp version 3
 ip igmp v3lite
 ip cgmp
 ip urd
end

...

interface Vlan39
 ...
 ip pim sparse-dense-mode
 ip igmp v3lite
 ip cgmp
 ip urd
