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.
