49 Multicast Listener Discovery and source specific multicast protocols (MLDv2) Setting the maximum response time You can define the maximum amount of time a multicast listener has to respond to queries by entering a command such as the following. BigIron RX(config)#ipv6 mld max-response-time 5 Syntax: ipv6 mld max-response-time Specify 1 - 64 for . The default is 5 seconds. Setting the last listener query count The Last Listener Query Count is the number of Multicast-Address- Specific Queries sent before the switch assumes there are no remaining listeners for an address on a link. You can set the last listener query count by entering a command such as the following. BigIron RX(config)#ipv6 mld llqc 5 Syntax: ipv6 mld llqc Specify 2 - 7 for . Setting the last listener query interval The Last Listener Query Interval is the Maximum Response Delay inserted into Multicast-Address-Specific Queries sent in response to Done messages, and is also the amount of time between Multicast- Address-Specific Query messages. When the device receives an MLDv1 leave message or an MLDv2 state change report, it sends out a query and expects a response within the time specified by this value. Using a lower value allows members to leave groups more quickly. You can set the last listener query interval by entering a command such as the following. BigIron RX(config)#ipv6 mld llqi 5 Syntax: ipv6 mld llqi Specify 1 - 10 for . Setting the robustness You can specify the number of times that the switch sends each MLD message from this interface. Use a higher value to ensure high reliability from MLD. You can set the robustness by entering a command such as the following. BigIron RX(config)#ipv6 mld robustness 3 Syntax: ipv6 mld robustness Specify 2 - 7 for . Default is 2 Setting the version You can use this command to set the MLD version (1 or 2) globally. You can select the version of MLD by entering a command such as the following. BigIron RX(config)#ipv6 mld version 2 1250 BigIron RX Series Configuration Guide 53-1001986-01

BigIron RX Series Configuration Guide

53-1001986-01

Multicast Listener Discovery and source specific multicast

protocols (MLDv2)

Setting the maximum response time

You can define the maximum amount of time a multicast listener has to respond to queries by

entering a command such as the following.

BigIron RX(config)#ipv6 mld max-response-time 5

Syntax:

ipv6 mld max-response-time <

seconds

Specify 1 – 64 for <

seconds

>. The default is 5 seconds.

Setting the last listener query count

The Last Listener Query Count is the number of Multicast-Address- Specific Queries sent before the

switch assumes there are no remaining listeners for an address on a link. You can set the last

listener query count by entering a command such as the following.

BigIron RX(config)#ipv6 mld llqc 5

Syntax:

ipv6 mld llqc <

seconds

Specify 2 – 7 for <

seconds

Setting the last listener query interval

The Last Listener Query Interval is the Maximum Response Delay inserted into

Multicast-Address-Specific Queries sent in response to Done messages, and is also the amount of

time between Multicast- Address-Specific Query messages. When the device receives an MLDv1

leave message or an MLDv2 state change report, it sends out a query and expects a response

within the time specified by this value. Using a lower value allows members to leave groups more

quickly. You can set the last listener query interval by entering a command such as the following.

BigIron RX(config)#ipv6 mld llqi 5

Syntax:

ipv6 mld llqi <

seconds

Specify 1 – 10 for <

seconds

Setting the robustness

You can specify the number of times that the switch sends each MLD message from this interface.

Use a higher value to ensure high reliability from MLD. You can set the robustness by entering a

command such as the following.

BigIron RX(config)#ipv6 mld robustness 3

Syntax:

ipv6 mld robustness<

seconds

Specify 2 – 7 for <

seconds
