Chapter 12: Multicast Routing Configuration Guide

Configuring IGMP

You configure IGMP on the SSR by performing the following configuration tasks:

•Creating IP interfaces

•Setting global parameters that will be used for all the interfaces on which DVMRP is enabled

•Configuring IGMP on individual interfaces. You do so by enabling and disabling IGMP on interfaces and then setting IGMP parameters on the interfaces on which IGMP is enabled

•Start the multicast routing protocol (i.e., DVMRP)

Configuring IGMP on an IP Interface

By default IGMP is disabled on the SSR.

To enable IGMP on an interface, enter the following command in Configure mode:

Enable IGMP on an interface.

igmp enable interface <ipAddr>

Configuring IGMP Query Interval

You can configure the SSR with a different IGMP Host Membership Query time interval. The interval you set applies to all ports on the SSR. The default query time interval is 125 seconds.

To configure the IGMP host membership query time interval, enter the following command in Configure mode:

Configure the IGMP host membership query time interval.

igmp set queryinterval <num>

Configuring IGMP Response Wait Time

You can configure the SSR with a wait time for IGMP Host Membership responses which is different from the default. The wait time you set then applies to all ports on the SSR. The default response time is 10 seconds.
