Chapter 14: Multicast Routing Configuration Guide
• Configuring DVMRP on individual interfaces. You do so by enabling and disabling
DVMRP on interfaces and then setting DVMRP parameters on the interfaces on which
DVMRP is disabled
• Defining DVMRP tunnels, which IP uses to send multicast traffic between two end
points
Starting and Stopping DVMRP
DVMRP is disabled by default on the SSR.
To start or stop DVMRP, enter one of the following commands in Configure mode:
Configuring DVMRP on an Interface
DVMRP can be controlled/configured on per-interface basis. An interface does not have
to run both DVMRP and IGMP together. DVMRP can be started or stopped; IGMP starts
and stops automatically with DVMRP.
To enable IGMP on an interface, enter the following command in the Configure mode:
Configuring DVMRP Parameters
In order to support backward compatibility, DVMRP neighbor timeout and prune time
can be configured on a per-interface basis. The default neighbor timeout is 35 seconds. The
default prune time is 7200 seconds (2 hours).
To configure neighbor timeout or prune time, enter one of the following commands in
Configure mode:
Start DVMRP. dvmrp start
Stop DVMRP. no dvmrp start
Enable DVMRP on an
interface. dvmrp enable interface |
Configure the DVMRP neighbor
timeout. dvmrp set interface neighbor-
timeout
Configure the DVMRP prune time. dvmrp set interface prunetime
