Mld Robust-Count - HP 3600 v2 Series Command Reference Manual

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 commands: mld send-router-alert and require-router-alert.
Examples
# Configure VLAN-interface 100 to discard MLD messages without the Router-Alert option.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] mld require-router-alert

mld robust-count

Syntax
mld robust-count robust-value
undo mld robust-count
View
Interface view
Default level
2: System level
Parameters
robust-value: Specifies an MLD querier's robustness variable, in the range of 2 to 5.
Description
Use mld robust-count to configure the MLD querier's robustness variable on the current interface.
Use undo mld robust-count to restore the default.
By default, the MLD querier's robustness variable is 2.
The MLD querier's robustness variable defines the maximum number of attempts for transmitting MLD
general queries, multicast-address-specific queries, or multicast-address-and-source-specific queries in
case of packet loss because of network problems. A greater value of the robustness variable makes the
MLD querier "more robust", but results in a longer IPv6 multicast group timeout time.
The MLD querier's robustness variable determines the following values:
The default number of MLD general queries the MLDv1/v2 querier sends on startup.
•
• The number of multicast-address-specific queries the MLDv1 querier sends after receiving an MLD
done message.
The number of multicast-address-and-source-specific queries the MLDv2 querier sends after
•
receiving an MLD report that tells relation changes between IPv6 multicast groups and IPv6
multicast sources.
Related commands: display mld interface, mld last-listener-query-interval, mld startup-query-count,
mld timer other-querier-present, mld timer query, and robust-count.
Examples
# Set the MLD querier's robustness variable to 3 on VLAN-interface 100.

[Sysname] interface vlan-interface 100
