>   For that purpose you need to use a tool like tcpdump or

>   processed hop-by-hop such that only the payload of the message is
>   preserved, but the IP header is replaced (i.e., the src IP address
>   won't match the BSR IP address).
> 
> * Check that the (unicast) reverse-path forwarding information in A
>   points to B as the next-hop toward C.

Forgot to mention that the xorpsh command for this check is:

show pim mrib
