Configuring MLD snooping port functions
Before you configure MLD snooping port functions, complete the following tasks:
• Enable MLD snooping for the VLAN.
• Determine the aging timer for dynamic router ports.
• Determine the aging timer for dynamic member ports.
• Determine the addresses of the IPv6 multicast group and IPv6 multicast source.
Setting aging timers for dynamic ports
When you set aging timers for dynamic ports, follow these guidelines:
• If the memberships of IPv6 multicast groups frequently change, set a relatively small value for the
aging timer of the dynamic member ports. If the memberships of IPv6 multicast groups rarely
change, you can set a relatively large value.
• If a dynamic router port receives an IPv6 PIMv2 hello message, the aging timer for the port is the
one in the hello message rather than the one set in the mld-snooping router-aging-time command
on the local device.
• You can set the aging timers for dynamic ports either for the current VLAN in VLAN view or globally
for all VLANs in MLD-snooping view. If configurations are made in both VLAN view and
MLD-snooping view, the configuration made in VLAN view takes priority.
