Configuring A Static Multicast Group - Cisco Catalyst 4500 Series Software Configuration Manual

Chapter 29 Configuring IPv6 Multicast Listener Discovery 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.
To add a Layer 2 port as a member of a multicast group, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# ipv6 mld snooping vlan
vlan-id static ipv6_multicast_address
interface interface-id
Step 3
Switch(config)# end
Step 4
Switch# show mac-address-table multicast
mld-snooping
Step 5
Switch# copy running-config startup-config
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 MAC address:
Switch# configure terminal
Switch(config)# ipv6 mld snooping vlan 2 static 3333.0000.0003 interface
gigabitethernet1/1
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.
Static connections to multicast routers are supported only on switch ports.
Note
To add a multicast router port to a VLAN, follow these steps:
Catalyst 4500 Series Switch, Cisco IOS Software Configuration Guide - Cisco IOS XE 3.9.xE and IOS 15.2(5)Ex
Purpose
Enters global configuration mode
Statically configures 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 64).
Returns to privileged EXEC mode.
Verifies the static member port and the IPv6 address.
(Optional) Saves your entries in the configuration file.
