Still struggling and clarification is appreciated...
As a summary,
When i configure the sparse mode with autorp listner when i specify
only one group
for RP everything is fine and showing as Sparse mode in sh ip mroute.
When i just joined another group which is not part of the RP
respinsible group, it is still pingable and showing as Dense mode.
Now my question is when i configure sparse mode with autorp listner,
still thoise groups not defined as RP responsible will fall in to
dense mode ?
Thanx
Regards

Hi
May be a stupid question. But i thought i better verify this.
Also I did not had the ip pim auto-rp listner command on my routers to
try this out.
Assuming that i have configured the following
1-multicast on all the routers
2-ip pim sparse mode on all the interface
3- enabled ip pim auto-rp listner on all the routers
4- One router say R3 is configured as RP (auto RP) for a specific
group 230.1.1.1
5- MA is already configured
Everything should work as expected...
Now if i have configured igmp-join for another group 225.5.5.5 on one
of the router.
Does the ping to this group will work ?
All routers will fall in to dense mode for this group even though
routers are configured for sparse only...
Will i see 224.0.1.40 and 224.0.1.39 in my mroute table ?
Thank you
Regards
