vrrp6 vrid track admin-vrrp6 vrid

Function

The vrrp6 vrid track admin-vrrp6 vrid command binds a VRRP6 group to an mVRRP6 group.

The undo vrrp6 vrid track admin-vrrp6 command unbinds a VRRP6 group from an mVRRP6 group.

By default, no VRRP6 group is bound to an mVRRP6 group.

Format

vrrp6 vrid virtual-router-id1 track admin-vrrp6 interface interface-type interface-number vrid virtual-router-id2 unflowdown

undo vrrp6 vrid virtual-router-id1 track admin-vrrp6

Parameters

Parameter	Description	Value
vrid virtual-router-id1	Specifies the VRID of a VRRP6 group.	The value is an integer that ranges from 1 to 255.
vrid virtual-router-id2	Specifies the VRID of an mVRRP6 group.	The value is an integer that ranges from 1 to 255.
interface-type interface-number	Specifies the type and number of an interface configured with an mVRRP6 group.	-
unflowdown	Allows the interface where a VRRP6 group bound to an mVRRP6 group is configured to retain the Up state if the mVRRP6 group is in Backup or Initialize state.	-

Usage Guidelines

Usage Scenario

If multiple VRRP6 groups are configured on the device, each group sends VRRP6 Advertisement packets to maintain its state machine. As a result, a large number of VRRP6 Advertisement packets are generated, which occupy network bandwidth resources and cause CPU performance to deteriorate. To solve the problem, run the vrrp6 vrid track admin-vrrp6 vrid command to bind a VRRP6 group to an mVRRP6 group. After a VRRP6 group is bound to an mVRRP6 group, the VRRP6 group does not send VRRP6 Advertisement packets to negotiate the Master and Backup states. The mVRRP6 group determines the status of the bound VRRP6 group. This method greatly reduces the impact of VRRP6 Advertisement packets on network bandwidth and CPU performance.

This mode is used on a network where uplink and downlink traffic can be transmitted along different paths. unflowdown can be configured to allow the mVRRP6 group to determine the status of its bound VRRP6 group. Uplink traffic travels through the master and then reaches the upper-layer network, and downlink traffic travels through either the master or backup to reach users.

Prerequisites

A VRRP6 group and an mVRRP6 group have been created.

Precautions

The vrrp6 vrid track admin-vrrp6 vrid command can be used only on the interface where the bound VRRP6 group is configured. This command cannot be used on the interface where an mVRRP6 group is configured.

VRRP4 and VRRP6 can be configured on an interface simultaneously. However, there are limitations:

A VRRP4 group can be bound to only an mVRRP4 group, and a VRRP6 group can be bound to only an mVRRP6 group.
At most one VRRP4 group and one VRRP6 group can be configured on an interface. An interface cannot be configured with multiple VRRP4 or VRRP6 groups.

# Bind VRRP6 group 1 to mVRRP6 group 2 on the Ethernet interface.
