Configuring MLD queries and responses in a VLAN
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN view. vlan vlan-id N/A
3. Set the MLD query interval.
mld-snooping query-interval
interval
125 seconds by default
4. Set the maximum response
time for MLD general queries. mld-snooping max-response-time
interval
10 seconds by default
5. Set the MLD last-member
query interval. mld-snooping
last-listener-query-interval interval 1 second by default
Configuring source IPv6 addresses of MLD queries
This configuration allows you to change the source IPv6 address of MLD queries.
To configure source IPv6 addresses of MLD queries:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN view. vlan vlan-id N/A
3. Configure the source IPv6
address of MLD general
queries.
mld-snooping general-query
source-ip { ipv6-address |
current-interface }
FE80::02FF:FFFF:FE00:0001 by
default
4. Configure the source IPv6
address of MLD
multicast-address-specific
queries.
mld-snooping special-query
source-ip { ipv6-address |
current-interface }
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
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
Enabling MLD snooping proxying
The MLD snooping proxying function works on a per-VLAN basis. After you enable the function in a
VLAN, the device works as the MLD snooping proxy for the downstream hosts and upstream router in the
VLAN.
