Can someone lab this up? I can tomorrow if no one else can. My thoughts on
an easy test:
Use dense mode
R1 has igmp static groups for a far side interface
R2 has ttl threshold command with links to R1 and R3
R3 sends mcast ping. On R3, configure the ttl of the ping to increase with
each test.
Test ping first before moving on.
Set the ttl threshnold on R2's link to R1. Increase the configured value
with each ping.
The ttl threshold is looking at the outgoing packets ... what is the ttl of
the outgoing packet? By the time the packet is an 'outgoing' packet, the
ttl has already been reduced by one ... would be best to lab this though to
see the command in action. I can tomorrow if no one else has this
available.
Also, if my quick test above is 'lame' ... please specify a better test and
I can try whatever you think is good tomorrow.
From the docs:
Usage Guidelines:
Only multicast packets with a TTL value greater than the threshold are
forwarded out the interface.
HTH,
TGIF. Have a good night team,
