■
b.b.b.b —IP address of the destination
■
c.c.c.c —IP address of the multicast group
■
d.d.d.d —IP address of the router to which the router sends the trace
■
Received mtrace response packet of length n —Length of the response packet,
in bytes
■
Each line of the trace has the following format: hops. ip-address Protocol:
protocol FwdingCode:forwarding code
■
hops —Number of hops from the destination to this intermediate router
■
ip-address —IP address of the intermediate router
■
protocol —Multicast protocol running on the intermediate router. A value
of 12 indicates IGMP; other values comply with A “ traceroute” Facility
for IP Multicast – draft-ietf-idmr-traceroute-ipm-07.txt .
■
FwdingCode —Forwarding information or error associated with this hop.
For example, RPF iif indicates that the request arrived on the expected
RPF interface for this source group. For more information about the
