ipv6 nd ns multicast-mac

Function

The ipv6 nd ns multicast-mac command configures the destination MAC address in the NS messages sent by the static users bound to the interface for IPv6 proactive detection as an IPv6 multicast address.

The undo ipv6 nd ns multicast-mac command restores the default configuration.

By default, the destination MAC address in the NS messages sent by the interface is a broadcast address.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

In some scenarios, terminals do not support the IPv6 address in an NS message as a multicast address, and the destination MAC address is a unicast or broadcast MAC address. As a result, the static users bound to the interface for IPv6 proactive protection fail to go online. To configure the destination MAC address in NS messages as a multicast MAC address, run the ipv6 nd ns multicast-mac command.

Configuration Impact

The destination MAC address in the NS messages sent by the static users bound to the interface for IPv6 proactive detection is changed to an IPv6 multicast MAC address.

Precautions

This command applies only to IPv6 proactive detection on static users.

Example

# On the BAS interface,configure the destination MAC address in the NS message as a multicast MAC address.
