1452 CHAPTER 92: MLD CONFIGURATION COMMANDS
Description Use the mld require-router-alert command to configure the interface to
discard MLD messages without the Router-Alert option.
Use the
undo mld require-router-alert command 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-count command to configure the MLD querier robustness
variable on the current interface.
Use the
undo mld robust-count command 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
