Chapter 38 Configuring IPv6 MLD Snooping
Configuring IPv6 MLD Snooping
To disable MLD snooping on a VLAN interface, use the no ipv6 mld snooping vlan vlan-id global
configuration command for the specified VLAN number.
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:
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.
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
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ipv6 mld snooping Globally enable MLD snooping on the switch.
Step 3
ipv6 mld snooping vlan vlan-id Enable MLD snooping on the VLAN.The VLAN ID range is 1 to
1001 and 1006 to 4094.
Note MLD snooping must be globally enabled for VLAN snooping
to be enabled.
Step 4
end Return to privileged EXEC mode.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enter global configuration mode
Step 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 48).
Step 3
end Return to privileged EXEC mode.
Step 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.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
