enable mld

enable mld {vlan vlan_name {MLDv1 | MLDv2} }

Description

Enables MLD on a router interface. If no VLAN is specified, MLD is enabled on all router interfaces.

Syntax Description


`vlan_name`	Specifies a VLAN name.
MLDv1	Sets the compatibility mode to MLDv1.
MLDv2	Sets the compatibility mode to MLDv2.

Default

Disabled.

Usage Guidelines

MLD is a protocol used by an IPv6 host to register its IPv6 multicast group membership with a router. Periodically, the router queries the multicast group to see if the group is still in use. If the group is still active, IPv6 hosts respond to the query, and group registration is maintained.

MLD is disabled by default on the switch. However, the switch can be configured to enable the generation and processing of MLD packets. If compatibility mode is not specified in the command, MLDv1 compatibility mode is set.

A VLAN must have an IPv6 address to support MLD.

Example

The following example enables MLDv1 on the VLAN accounting:

enable mld vlan accounting
