To do... Use the command... Remarks
Configure MLD query interval
mld-snooping query-interval
interval Optional
125 seconds by default
Configure the maximum response
time for MLD general queries mld-snooping max-response-time
interval Optional
10 seconds by default
Configure the MLD last-member
query interval mld-snooping
last-listener-query-interval interval
Optional
1 second by default
CAUTION:
Be sure to configure the MLD query interval greater than the maximum response time for MLD general
queries. Otherwise, unexpected deletion of IPv6 multicast members might occur.
Configuring source IPv6 addresses of MLD queries
This configuration allows you to change the source IPv6 address of MLD queries.
Follow these steps to configure source IPv6 addresses of MLD queries:
To do... Use the command... Remarks
Enter system view system-view —
Enter VLAN view vlan vlan-id —
Configure the source IPv6 address
of MLD general queries
mld-snooping general-query
source-ip { ipv6-address |
current-interface }
Optional
FE80::02FF:FFFF:FE00:0001 by
default
Configure the source IPv6 address
of MLD multicast-address-specific
queries
mld-snooping special-query
source-ip { ipv6-address |
current-interface }
Optional
FE80::02FF:FFFF:FE00:0001 by
default
CAUTION:
The source IPv6 address of MLD query messages might affect MLD querier election within the segment.
Configuring MLD snooping proxying
Configuration prerequisites
Before you configure MLD snooping proxying in a VLAN, complete the following tasks:
• Enable MLD snooping in the VLAN
• Determine the source IPv6 address for the MLD reports sent by the proxy
• Determine the source IPv6 address for the MLD done messages sent by the proxy
