Multicast configuration driving me nuts

[dtdamen]

Hi Silvio,
there is nothing I can see for output. No life, no counter, nothing
Not on the core and not on the 6560 switches
No idea what´s wrong in my configuration.

At this point I'd open an SR with ALE.
I always do it the same way as Silvio. Globally.

Core:

Code: Select all

ip multicast admin-state enable
ip multicast version 3
ip multicast querier-forwarding enable
ip multicast querying enable

Edge:

Code: Select all

ip multicast admin-state enable
ip multicast version 3
ip multicast querier-forwarding enable

We never needed to use 'proxy' or 'spoofing', and sometimes we use 'zapping' on the Edge switches for IPTV as well.
That's it. I dont even know the exact use case for proxy and spoofing, but I know spoofing causes VoIP issues according to my colleagues.

In terms of show commands, you need to see info with:
show ip multicast group/neighbor/forward/querier
(what groups I'm in / what neighbors I have / what I forwarded to others / who is the querier)
