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.
