ipv6 icmp multicast-address echo receive (interface view)

Function

The ipv6 icmp multicast-address echo receive command enables a device to respond or disables a device from responding to ICMPv6 multicast Echo messages received on an interface.

The undo ipv6 icmp multicast-address echo receive command restores the default configuration in the interface view.

By default, if a device is not disabled from responding to received ICMPv6 multicast Echo messages in the system view, it responds to ICMPv6 multicast Echo messages received on an interface; if a device is disabled from responding to received ICMPv6 multicast Echo messages in the system view, it does not respond to ICMPv6 multicast Echo messages received on an interface.

Format

ipv6 icmp multicast-address echo receive { disable | enable }

undo ipv6 icmp multicast-address echo receive [ disable | enable ]

Parameters

disable	Disables a device from responding to ICMPv6 multicast Echo messages received on an interface.	-

Usage Guidelines

Usage Scenario

If a routing device or an interface receives a large number of ICMPv6 multicast Echo messages, responding to these messages consumes performance. To disable a device from responding to ICMPv6 multicast Echo messages received on a specified interface, run the ipv6 icmp multicast-address echo receive disable command. To disable a device from responding to ICMPv6 multicast Echo messages received globally and enable a device to respond to ICMPv6 multicast Echo messages received on a specified interface, run the ipv6 icmp multicast-address echo receive disable command in the system view and the ipv6 icmp multicast-address echo receive enable command in the interface view. In this way, the performance consumption caused by responding to the messages can be reduced.

Precautions

Priority of enabling an interface to respond or disabling an interface from responding to received ICMPv6 multicast Echo messages:

The configuration in the interface view takes precedence over the configuration in the system view.

Example

# Disable a device from responding to ICMPv6 multicast Echo messages received on an interface.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet0/1/1
[~HUAWEI-GigabitEthernet0/1/1] ipv6 enable
[*HUAWEI-GigabitEthernet0/1/1] ipv6 icmp multicast-address echo receive disable
