Chapter 14: MULTICAST COMMANDS

This chapter explains how to use the multicast commands in the 8.0 CLI. Use the multicast commands to
configure an Avaya Secure Router 3120 for mtrace, Internet Group Management Protocol (IGMP), and
sparse mode Protocol Independent Multicast (PIM).
ip igmp
Enables IGMP (Internet Group Management Protocol) on the associated interface with the
default set of configurations. Use the no form of this command to disable IGMP on the interface.
IGMP is not enabled by default.
syntax:
[no] ip igmp
Operating Mode:
Interface
example:
To enable IGMP for interface ethernet 1/0, enter:
SR/configure/ip/igmp> interface ethernet 1/0
applies to:
All modules
ip igmp ignore-v1-messages
Controls processing of all IGMPv1 messages on the associated interface. Note that this breaks
interoperability with older IGMPv1 users on the network and should be employed when it is
important to maintain small group leave latencies. This command is only effective for IGMPv3
and IGMPv2. This command is disabled by default.
syntax:
[no] ip igmp ignore-v1-messages
