1336 CHAPTER 87: MULTICAST ROUTING AND FORWARDING CONFIGURATION COMMANDS

static route to check whether the route has been successfully configured or whether the route has taken effect.

Related command: display multicast routing-table static.

Example # 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> system-view

[Sysname] ip rpf-route-static 10.1.1.1 24 192.168.1.23

mtracert

Syntax mtracert source-address [ [ last-hop-router-address ] group-address ]

View Any view

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.

Description Use the mtracert command to trace the path down which the multicast traffic from a given multicast source flows to the last-hop router.

Note that if the last-hop-router-addressargument 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.

Examples # 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.

<Sysname> mtracert 6.6.6.6 5.5.5.8 225.2.1.1 Type Ctrl+C to quit mtrace facility

Tracing reverse path of (6.6.6.6, 225.2.1.1) from last-hop router (5

.5.5.8) to source via multicast routing-table

-1 5.5.5.8

Incoming interface address: 4.4.4.8

Previous-hop router address: 4.4.4.7

Input packet count on incoming interface: 17837

Output packet count on outgoing interface: 0

Total number of packets for this source-group pair: 8000

Protocol: PIM

Forwarding TTL: 0

Forwarding code: No error
