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.

4.3 Configuring Basic IGMP Functions
The global configuration is valid on each interface.
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.
