Configuring IPv6 MLD Snooping

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.

Beginning in privileged EXEC mode, follow these steps to add a Layer 2 port as a member of a multicast group:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode
Step 2
	ipv6 mld snooping vlan vlan-idstatic	Statically configure a multicast group with a Layer 2 port as a
	ipv6_multicast_address interface interface-id	member of a multicast group:
		• vlan-idis 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-idis the member port. It can be a physical
		interface or a port channel (1 to 48).
Step 3
	end	Return to privileged EXEC mode.
Step 4 show ipv6 mld snooping multicast-address user		Verify the static member port and the IPv6 address.
	or
	show ipv6 mld snooping multicast-address vlan
	vlan-id user
Step 5
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To remove a Layer 2 port from the multicast group, use the no ipv6 mld snooping vlan vlan-idstatic mac-addressinterface interface-idglobal configuration command. If all member ports are removed from a group, the group is deleted.

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 gigabitethernet1/0/1

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.

Note Static connections to multicast routers are supported only on switch ports.
