admin-vrrp vrid

Function

The admin-vrrp vrid command creates a management Virtual Router Redundancy Protocol (mVRRP) group or designates a common VRRP group as an mVRRP group.

The undo admin-vrrp vrid command deletes an mVRRP group or restores an mVRRP group with a virtual IP address to a common VRRP group.

By default, no mVRRP group is configured.

Format

admin-vrrp vrid virtual-router-id [ ignore-if-down ]

undo admin-vrrp vrid virtual-router-id

Parameters

Parameter	Description	Value
ignore-if-down	Indicates that an mVRRP group ignores an interface Down event. If an interface on which an mVRRP group is configured goes Down, the status of the mVRRP group becomes Master, not Initialize.	-
vrid virtual-router-id	Specifies the ID of an mVRRP group.	The value is an integer ranging from 1 to 255.

Parameter

Description

Value

ignore-if-down

Indicates that an mVRRP group ignores an interface Down event.

If an interface on which an mVRRP group is configured goes Down, the status of the mVRRP group becomes Master, not Initialize.

vrid virtual-router-id

Specifies the ID of an mVRRP group.

The value is an integer ranging from 1 to 255.

Usage Guidelines

Usage Scenario

A lot of VRRP packets are sent by multiple master devices when multiple common VRRP groups are configured. The VRRP packets consume network bandwidth resources and burden the system. The admin-vrrp vrid command can be run to configure an mVRRP group. The mVRRP group sends VRRP packets and determines the status of services VRRP groups that are bound to the mVRRP group. Using mVRRP reduces resource consumption.

An mVRRP group functioning as a gateway processes both protocol and service packets. An mVRRP group that does not function as a gateway processes only protocol packets.
Before a VRRP group is bound to an mVRRP group, the VRRP group is a common VRRP group and is able to process both protocol and service packets.
After the VRRP group is bound to the mVRRP group, the VRRP group becomes a service VRRP group and is able to process only service packets.
ignore-if-down must be configured in the admin-vrrp vrid command in the following scenario:
If a user-side device cannot broadcast packets, mVRRP can be enabled on directly connected interfaces on devices in a VRRP group. The master device sends VRRP packets along the direct link.If a device on one end of the direct link fails, the VRRP-enabled interface on the other device also goes Down. The mVRRP status on both devices becomes Initialize, causing service packet interruptions. To prevent the preceding problem, specify the ignore-if-down parameter in the admin-vrrp vridvrrp vrid admin command on both the master and backup devices. The parameter enables the mVRRP group to ignore the event that a directly connected interface goes Down. This setting allows the VRRP-enabled interface on one end of the direct link to continue forwarding service packets if the VRRP-enabled interface on the other end goes Down.
Using an inter-board trunk interface is recommended to improve intermediate link reliability when mVRRP is enabled on two directly connected interfaces. Do not run the shutdown command on either of the directly connected interfaces, preventing them from both entering the Master state.

Prerequisites

A VRRP group has been created using the vrrp vrid virtual-ip command in the interface view if an mVRRP group is used as a gateway.

Follow-up Procedure

After the admin-vrrp vrid command is run, run the vrrp vrid track admin-vrrp command on the interface on which a service VRRP group is configured to bind the service VRRP group to the mVRRP group.

Precautions

After the undo admin-vrrp vrid command is run to delete an mVRRP group, the associations between service VRRP groups and the mVRRP group are automatically deleted.
