Configuring IPv6 static multicast MAC address entries
In Layer-2 multicast, a Layer-2 IPv6 multicast protocol (such as MLD snooping) can dynamically add IPv6
multicast MAC address entries. Or, you can manually configure IPv6 multicast MAC address entries.
Configuration guidelines
• Any legal IPv6 multicast MAC address except 3333-xxxx-xxxx (where x represents a hexadecimal
number from 0 to F) can be manually added to the MAC address table. IPv6 multicast MAC
addresses are the MAC addresses in which the least significant bit of the most significant octet is 1.
• When you configure a static multicast MAC address entry in system view, the configuration takes
effect on the specified interface. When you configure a static multicast MAC address entry in
interface view or port group view, the configuration takes effect on only the current interface or
interfaces in the current port group.
Configuration procedure
To configure an IPv6 static multicast MAC address entry in system view:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a static multicast
MAC address entry.
mac-address multicast
mac-address interface interface-list
vlan vlan-id
No static multicast MAC address
entries exist by default.
