Configuring A Downstream Interface; Configuring An Igmp Multicast Agent - HP ProCurve Secure Router 7203 dl Advanced Management And Configuration Manual

Configuring a Downstream Interface

First, move to the configuration mode context for the interface:
Syntax: interface <interface ID>
For example:
ProCurve(config)# int eth 0/1
A downstream interface typically should perform three functions:
IGMP multicast agent—send IGMP queries and listen for IGMP messages
IGMP proxy—forward IGMP messages to a remote multicast server
multicast forwarding—forward multicast messages if the corresponding
host group exists on the connecting network

Configuring an IGMP Multicast Agent

This command both enables the interface to run IGMP and to forward multi-
cast messages:
ProCurve(config-eth 0/1)# ip mcast-stub downstream
The interface will send IGMP queries and listen for reports and leave messages
to determine which host groups are active on its network.
By default, downstream interfaces run IGMP version 2. You can change the
version an interface uses with this command, entered from a logical interface
configuration mode context:
Syntax: ip igmp version [1 | 2]
For example, if your network used version 1, you could configure an Ethernet
interface to run IGMP version 1:
ProCurve(config-eth 0/1)# ip igmp version 1
You can also alter settings such as how often the interface issues IGMP queries
and how long it waits after a group membership expires to remove that group
from its IGMP table. These configuration tasks are aimed at containing
packets and are not necessary. (See "Altering IGMP Query Intervals" on
page 10-16.)
