Configuring a Static Multicast Group
Hosts or Layer 2 ports normally join multicast groups dynamically, but you can also statically configure an IPv6 multicast
address and member ports for a VLAN. Follow this procedure to add a Layer 2 port as a member of a multicast group.
DETAILED STEPS
To remove a Layer 2 port from the multicast group, use the no ipv6 mld snooping vlan vlan-id static mac-address
interface interface-id global configuration command. If all member ports are removed from a group, the group is
deleted.
EXAMPLE
This example shows how to statically configure an IPv6 multicast group:
Switch# configure terminal
Switch(config)#
ipv6 mld snooping vlan 2 static FF12::3 interface gigabitethernet0/1
Switch(config)# end
Configuring a Multicast Router Port
Although MLD snooping learns about router ports through MLD queries and PIMv6 queries, you can also use the
command-line interface (CLI) to add a multicast router port to a VLAN. To add a multicast router port (add a static
connection to a multicast router), use the
ipv6 mld snooping vlan mrouter global configuration command on the switch.
BEFORE YOU BEGIN
Static connections to multicast routers are supported only on switch ports.
Table 46-14
Command Purpose
1. configure terminal Enter global configuration mode
2. ipv6 mld snooping vlan vlan-id static
ipv6_multicast_address interface
interface-id
Statically configure a multicast group with a Layer 2 port
as a member of a multicast group:

vlan-id is the multicast group VLAN ID. The VLAN ID
range is 1 to 1001 and 1006 to 4094.

ipv6_multicast_address is the 128-bit group IPv6
address. The address must be in the form specified
in RFC 2373.

interface-id is the member port. It can be a physical
interface or a port channel (1 to 10).
3. end Return to privileged EXEC mode.
4. show ipv6 mld snooping
multicast-address user
or
show ipv6 mld snooping
multicast-address vlan vlan-id user
Verify the static member port and the IPv6 address.
5. copy running-config startup-config (Optional) Save your entries in the configuration file.
