Information
Mtrace is an IGMP protocol based on the Multicast trace route facility and
implemented according to the IETF draft “A trace route facility for IP Multicast”
(draft-fenner-traceroute-ipm-01.txt). FTOS supports the Mtrace client and transmit
functionality.
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.
