4.4 Setting the Parameters of IGMP Features
This section describes how to set the parameters of IGMP features.
Context
By default, IGMP can work normally. In the S7700, you can change the values of related
parameters according to the specific network environment. You can perform the following
configurations as required.
NOTE
l The configuration in the IGMP view is valid globally. The configuration in the interface view is valid
only for the specific interface.
l If this command is configured in the interface view and the IGMP view, the values set in the interface
view are preferred. If this command is not configured in the interface view, the values configured in
the IGMP view are valid.
4.4.1 Establishing the Configuration Task
Applicable Environment
IGMPv2 and IGMPv3 have the Group-Specific and Source/Group-Specific Query messages.
The groups are varied and an S7700 cannot join all groups. Therefore, the IGMP needs to use
the Router-Alert option. Then the IGMP can send messages for the groups that the local device
does not join to the upper protocol for processing.
The IGMP querier periodically sends IGMP Query messages on the shared network connected
to receivers. When receiving a Report message from a member, the querier updates information
about the membership. If non-queriers do not receive any General Query message within the
Keepalive period of the IGMP querier, the querier is considered faulty, and a new round of the
querier election is triggered automatically.
In some cases, one host matches a port. Therefore, a querier matches only one receiver host.
When a receiver host switches between multiple groups frequently, you can enable the prompt
leave mechanism on the querier.
