Yes, and specifically, at the head the mroute has only an accepting interface,

Hi Neale,
Here is the output of "show mpls fib 501" on the tail node (encapsulation is
happening at the head node where rpf_id is set as 0, JFYI)

Hi Neale,
Sure, I will push this and other multicast options in the CLIs shortly.
Meanwhile, here is the output from gdb:

This is done in fib_path_resolve if the path is flagged as RPF_ID, which yours
is not…

Hi
Hi,
Just wanted to understand if the following things are achievable with VPP
w.r.t IP multicast:
1. Ip multicast routing - check (S, G) and forward to one or more listeners
2. Ip multicast MPLS tunnel origination - check (S,G) and replicate to one
or more MPLS tunnels (with different labels)
3.
26 matches
