1452 CHAPTER 92: MLD CONFIGURATION COMMANDS

Description Use the mld require-router-alertcommand to configure the interface to discard MLD messages without the Router-Alert option.

Use the undo mld require-router-alertcommand to restore the default configuration.

By default, the device does not check the Router-Alert option, that is, it forwards all received MLD messages to the upper layer protocol for processing.

Related command: require-router-alert (MLD view) and mld send-router-alert.

Example # Configure Ethernet1/0 to discard MLD messages without the Router-Alert option.

<Sysname> system-view

[Sysname] interface ethernet 1/0

[Sysname-Ethernet1/0] mld require-router-alert

mld robust-count

Syntax mld robust-count robust-value

undo mld robust-count

View Interface view

Parameter robust-value: MLD querier robustness variable, with an effective range of 2 to 5. The MLD robustness variable determines the number of general queries the MLD querier sends on startup and the number of MLD group-specific queries the MLD querier sends upon receiving an MLD done message.

Description Use the mld robust-countcommand to configure the MLD querier robustness variable on the current interface.

Use the undo mld robust-countcommand to restore the system default.

By default, the MLD robustness variable is 2.

Related command: robust-count (MLD view), mld timer query, mld last-listener-query-interval,mld timer other-querier-present, and display mld interface.

Example # Set the MLD querier robustness variable to 3 on Ethernet 1/0.

<Sysname> system-view

[Sysname] interface ethernet 1/0

[Sysname-Ethernet1/0] mld robust-count 3
