To do...
Set the MLD last-member query
interval
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...
Enter system view
Enter VLAN view
Configure the source IPv6 address
of MLD general queries
Configure the source IPv6 address
of MLD multicast-address-specific
queries
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
•
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.
Follow these steps to enable MLD snooping proxying in a VLAN:
Use the command...
mld-snooping last-listener-query-
interval interval
Use the command...
system-view
vlan vlan-id
mld-snooping general-query
source-ip { ipv6-address | current-
interface }
mld-snooping special-query
source-ip { ipv6-address | current-
interface }
