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:
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:
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.
Enable IGMP on an interface. igmp enable interface
Configure the IGMP host
membership query time interval. igmp set queryinterval
