OUTING AND ORWARDING
static route to check whether the route has been successfully configured or
whether the route has taken effect.
display multicast routing-table static.
# Configure a multicast static route to the multicast source 10.1.1.1/24, specifying
a router with the IP address of 192.168.1.23 as its RPF neighbor.

[Sysname] ip rpf-route-static 10.1.1.1 24 192.168.1.23
mtracert source-address [ [ last-hop-router-address ] group-address ]
Any view
source-address: Specifies a multicast source address.
group-address: Specifies a multicast group address, in the range of 224.0.1.0 to
239.255.255.255.
last-hop-router-address: Specifies a last-hop router address, which is the IP address
of the local router by default.
Use the command to trace the path down which the multicast traffic
mtracert
from a given multicast source flows to the last-hop router.
Note that if the last-hop-router-address argument is given in the command to
trace the path for a specific (S, G) multicast stream, the interface corresponding to
the last-hop router address must be the outgoing interface for the (S, G) multicast
stream; otherwise the multicast traceroute will fail.
# Trace the path down which the (6.6.6.6, 225.2.1.1) multicast traffic flows from
the multicast source to the last-hop router with the (S, G) outgoing interface
address of 5.5.5.8.
