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:

Start DVMRP.

dvmrp start

 

 

Stop DVMRP.

no dvmrp start

 

 

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:

Enable DVMRP on an interface.

dvmrp enable interface <ipAddr><interface-name>

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:

Configure the DVMRP neighbor

dvmrp

set

interface <ip-addr>neighbor-

timeout.

timeout <number>

 

 

 

 

Configure the DVMRP prune time.

dvmrp

set

interface <ip-addr>prunetime

 

<number>
