ipv6 mld tracking

Enables multicast listening discovery (MLD) tracking on a virtual interface.
Syntax
ipv6 mld tracking
no ipv6 mld tracking
Command Default

Multicast tracking is disabled on the virtual interface.

Modes

Virtual interface configuration mode

Usage Guidelines

The no form of this command restores the default; tracking is disabled.

When MLD tracking is enabled, a Layer 3 device tracks all clients that send membership reports. When a Leave message is received from the last client, the device immediately stops forwarding to the physical port, without waiting 3 seconds to confirm that no other clients still want the traffic.

Examples

This example enables multicast tracking on a virtual interface. 

device# configure terminal
device(config)# interface ve 13
device(config-vif-13)# ipv6 mld tracking
