Huawei quidway s7700 - Configuring IGMP Message Options

Pre-configuration Tasks
Before configuring IGMP message options and timers, complete the following tasks:
l Configuring the unicast routing protocol to make the IP routes of nodes be reachable
l 4.3 Configuring Basic IGMP Functions
Data Preparation
To configure IGMP message options and related timers, you need the following data.
No. Data
1 Whether the Router-Alert option is contained
in the packet
2 Interval for sending IGMP General Query
messages
3 IGMP robustness variable
4 Maximum response duration of the IGMP
Query messages
5 Keepalive period of the other IGMP queriers
6 Interval for sending IGMP Group-Specific
Query messages
7 ACL that limits the application range of
prompt leave
4.4.2 Configuring IGMP Message Options
Context
The Router-Alert option requires the S7700 to send the received IGMP messages that have not
been added to IGMP groups to the upper layer protocol. By default, the S7700 sends IGMP
messages containing the Router-Alert option, but does not check the Router-Alert option in the
received messages. That is, the S7700 processes all the received IGMP messages, regardless
whether the messages contain the Router-Alert option. If require-router-alert is configured,
the S7700 checks this option.
The Router-Alert option can be configured globally or on an interface.
l The global configuration is valid on each interface.
l The configuration on an interface is valid only for the specific interface. The configuration
on an interface takes precedence over the global configuration. If the Router-Alert option
is not configured on the interface, the global configuration is used.
Procedure
l Configuring IGMP message options globally
