Associating Track with VRRP

When VRRP is operating in standard mode or load balancing mode, associate the Track module with
the VRRP group to implement the following actions:
•
Change the priority of a router according to the status of the uplink. If a fault occurs on the uplink
of the router, the VRRP group is not aware of the uplink failure. If the router is the master, hosts
in the LAN cannot access the external network. To resolve this problem, configure the detection
module-Track-VRRP collaboration. The detection module monitors the status of the uplink of
the router and notifies the Track module of the detection result.
When the uplink fails, the detection module notifies the Track module to change the status of
the monitored track entry to Negative. The priority of the master decreases by a user-specified
value. A router with a higher priority in the VRRP group becomes the master.
•
Monitor the master on a backup. If a fault occurs on the master, the backup operating in
switchover mode will switch to the master immediately to maintain normal communication.
When VRRP is operating in load balancing mode, associate the Track module with the VRRP VF to
implement the following functions:
•
Change the priority of the AVF according to its uplink state. When the uplink of the AVF fails, the
track entry changes to Negative state. The weight of the AVF decreases by a user-specified
value. The VF with a higher priority becomes the new AVF to forward packets.
•
Monitor the AVF status from the LVF. When the AVF fails, the LVF that is operating in switchover
mode becomes the new AVF to ensure continuous forwarding.
When you associate Track with VRRP, follow these restrictions and guidelines:
•
The vrrp vrid track priority reduced or vrrp vrid track switchover command does not take
effect on an IP address owner. The command takes effect when the router does not act as the
IP address owner.
An IP address owner is the router with its interface IP address used as the virtual IP address of
the VRRP group.
•
When the status of the track entry changes from Negative to Positive or NotReady, one of the
following events occurs:
The master router automatically restores its priority.
Command
•
Associate Track with the interface
management module to monitor the
link status of an interface:
track track-entry-number interface
interface-type interface-number
[ delay { negative negative-time |
positive positive-time } * ]
•
Associate Track with the interface
management module to monitor the
network-layer protocol status of an
interface:
track track-entry-number interface
interface-type interface-number
protocol { ipv4 | ipv6 } [ delay
{ negative negative-time | positive
positive-time } * ]

Remarks
By default, no track entry
is created.
