direct-route track vrrp interface

Function

The direct-route track vrrp interface command associates direct routes with a Virtual Router Redundancy Protocol (VRRP) backup group in the loopback interface view.

The undo direct-route track vrrp interface command deletes the association between direct routes and a VRRP group in the loopback interface view.

By default, direct routes are not associated with a VRRP group.

Format

direct-route track vrrp interface { interface-name | interface-type interface-number } vrid virtual-router-id degrade-cost cost-value

undo direct-route track vrrp [ interface { interface-name | interface-type interface-number } vrid virtual-router-id degrade-cost cost-value ]

Parameters

Parameter	Description	Value
interface-type	Specifies the type of the interface on which a VRRP group is configured.	-
interface-number	Specifies the number of the interface on which a VRRP group is configured.	-
vrid virtual-router-id	Specifies the ID of a VRRP group.	The value is an integer ranging from 1 to 255.
degrade-cost cost-value	Specifies a cost to be applied to IP direct routes when the associated VRRP group is in the Backup or Initialize state.	The value is an integer ranging from 1 to 4294967295.

Usage Guidelines

Usage Scenario

Two CloudEdge-GWs in equipment room run VRRP, which is deployed on Eth-Trunk interfaces. Packets are transparently transmitted through an AGG-SW. The priority of network segment routes on loopback interfaces is associated with the VRRP status, and the priority of network segment routes on loopback interfaces of the CloudEdge-GW in the Backup state is low.

Prerequisites

VRRP has been configured on interfaces.

Configuration Impact

After the direct-route track vrrp interface command is run, the cost of IP direct routes is adjusted based on the VRRP group status, with details as follows:

If the VRRP group status is Master, 0 is used as the cost of the IP direct routes. The IP direct routes have the highest priority.
If the VRRP group status is Backup or Initialize, the cost-value specified in the command is used as the cost of the IP direct routes.

Follow-up Procedure

Configure a dynamic routing protocol to import the direct routes.

Precautions

You can run only one direct-route track vrrp interface command on a loopback interface. Before associating the direct routes with the VRRP group specified by vrid in another direct-route track vrrp interface command, you must delete the original direct-route track vrrp interface command.

Example

# Associate the direct routes on loopback1 with a VRRP group.
