Command Modes EXEC Privilege Command History Version 7.5.1.0 Expanded to support originator Version 7.4.1.0 Expanded to support intermediate (transit) router E-Series legacy command Usage 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. Multicast | 963
