Chapter 14: Multicast Routing Configuration Guide

To configure the host response wait time, enter the following command in Configure mode:

Configure the IGMP host response wait time.

igmp set responsetime <num>

Configuring Per-Interface Control of IGMP Membership

You can configure the SSR to control IGMP membership on a per-interface basis. An interface can be configured to be allowed or not allowed membership to a particular group.

To configure the per-interface membership control, enter the following commands in Configure mode:

Allow a host group member-

igmp

set

interface <name/ip-addr>allowed-

ship to a specific group.

groups <ip-addr/subnet mask>

 

 

 

 

Disallow a host group member-

igmp

set

interface <name/ip-addr> not-

ship to a specific group.

allowed-groups<ip-addr/subnet mask>

 

 

 

 

Configuring Static IGMP Groups

If IGMP is enabled on an interface, at least one group member needs to be present on the interface for the SSR to retain the group on its list of multicast group memberships for the interface. You can configure a static IGMP group for an interface; a static group can exist without any group members present on the interface.

To configure a static IGMP group on an interface, enter the following command in Configure mode:

Configure a static IGMP group on an interface.

igmp join group <ip-addr/subnet mask> interface <name/ip-addr>

Configuring DVMRP

You configure DVMRP routing on the SSR by performing the following DVMRP- configuration tasks:

Creating IP interfaces

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