Configuring IP Multicast Protocols
December 2000 18 - 53
Figure 18.8 Example multicast static routes
To add a static route to a virtual interface, enter commands such as the following:
BigIron(config)# mroute 3 0.0.0.0 0.0.0.0 int ve 1 distance 1
BigIron(config)# write memory
USING THE WEB MANAGEMENT INTERFACE
You cannot configure a static multicast route using the Web management interface.
Tracing a Multicast Route
The Foundry implementation of Mtrace is based on “A ‘traceroute’ facility for IP Multicast”, an Internet draft by S.
Casner and B. Fenner. To trace a PIM route, use the following CLI method.
NOTE: This feature is not supported for DVMRP.
USING THE CLI
To trace a PIM route to PIM source 209.157.24.62 in group 239.255.162.1, enter a command such as the
following:
BigIron# mtrace source 209.157.24.62 group 239.255.162.1
