Hey, Victor. For the next hop you might want to use the show ip pim neighbor
command. HTH.

Subject: Next hop IP address required
Hello List, is there any way to know which is the next hop for ip mroute
in a multi-access media??
I have a multicast topology like this
228.22.22.22 |==E0= R2 -S0---------S0-R5 -S1 ----S0-- R1 =E0 ==== E0 =
R3-- |
All the interfaces are running ip pim sparse-dense-mode, and the problem
is that the RPF Fails, because there is a ppp link between R2 and R3 and
the unicast routing prefers that link to reach destinations in R3/R2, so
where do you put the ip mroute 0.0.0.0 255.255.255.255 (on R2 or R3?)
and which is the next hop required?
