Multicast | 1009
As an Mtrace client, FTOS transmits Mtrace queries, receives, parses and prints out the
details in the response packet received.
As an Mtrace transit or intermediate router, FTOS returns the response to Mtrace queries.
Upon receiving the Mtrace request, FTOS computes the RPF neighbor for the source, fills in
the request and the forwards the request to the RPF neighbor. While computing the RPF
neighbor, the static mroute and mBGP route is preferred over the unicast route.
