configure mld

configure mld query_interval query_response_interval last_member_query_interval {{vlan} vlan_name} {{vr} vr_name} {robustness}

Description

Configures the Multicast Listener Discovery (MLD) timers.

Syntax Description

query_interval Specifies the interval (in seconds) between general queries.
query_response_interval Specifies the maximum query response time (in seconds).
last_member_query_interval Specifies the maximum group-specific query response time (in seconds).
vlan_name Applies the configuration only to the specified VLAN (Virtual LAN). If no VLAN is specified, the configuration appliese to all VLANs.
vr_name Specifies the VR to which the configuration should be applied. If not parameter is specified, the configuration is applied to the current VR context.
robustness Specifies the degree of robustness for the network.

Default

  • query interval—125 seconds
  • query response interval—10 seconds
  • last member query interval—1 second
  • robustness—2

Usage Guidelines

Timers are based on RFC2710. Specify the following:
  • query interval—The amount of time, in seconds, the system waits between sending out general queries. The range is 1 to 429,496,729 seconds.
  • query response interval—The maximum response time inserted into the periodic general queries. The range is 1 to 25 seconds.
  • last member query interval—The maximum response time inserted into a group-specific query sent in response to a leave group message. The range is 1 to 25 seconds.
  • robustness—The degree of robustness of the network. The range is 2 to 7.

Example

The following command configures the MLD timers:

configure mld 100 5 1 3
