Hello!

You can use the mtrace command to detect the multicast or RPF path from a multicast source to the querier or to a destination host. The querier indicates the router on which the mtrace command is executed.

Example

# Detect the multicast path from the multicast source 10.1.0.1 to the destination 225.0.0.1. The destination host address is 10.1.6.4, the querier is directly connected to the destination host, the response address is the default value 224.0.1.32 and the TTL value of a Response packet is 5.

<Huawei> mtrace -b -r 10.1.6.4 -g 225.0.0.1 -tr 5 source 10.1.0.1

 Press Ctrl+C to break multicast traceroute facility

 From the receiver(10.1.6.4), trace (10.1.0.1, 225.0.0.1)'s reverse path according to multicast routing-table

 Num  Reverse-Path    FwdTTL Protocol

  0   10.1.6.4

 -1   10.1.5.1        1      PIM

 -2   10.1.2.1        1      PIM

 -3   10.1.0.1        1      PIM

In maximum-hop mode, received the response message and the multicast traceroute finished.

I hope this helps!
