562
Because outgoing interface iteration might fail or the specified interface might be in down state, the static
multicast route configured with this command might fail to take effect. Therefore, after you configure a
static multicast route, use the display multicast routing-table static command to verify that the route has
been successfully configured or whether the route has taken effect.
Examples
# Configure a static multicast route to the multicast source 10.1.1.1/24. Specify a router with the IP
address of 192.168.1.23 as its RPF neighbor.
<Sysname> system-view
[Sysname] ip rpf-route-static 10.1.1.1 24 192.168.1.23

mtracert
Use mtracert to trace the path down which the multicast traffic flows to the last-hop router.
Syntax
mtracert source-address [ [ last-hop-router-address ] group-address ]
Views
Any view
Default command level
1: Monitor level
Parameters
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.
Usage guidelines
If the command to trace the path for a specific (S, G) multicast stream includes the last-hop-router-address
argument, the interface that corresponds to the last-hop router address must be the outgoing interface for
the (S, G) entry. Otherwise, the multicast traceroute might fail.
Examples
# Trace the path down which the (6.6.6.6, 225.2.1.1) multicast traffic flows to the last-hop router with an
IP address of 5.5.5.8.
<Sysname> mtracert 6.6.6.6 5.5.5.8 225.2.1.1
