Configuring route tracking on an exit path network and setting a priority on a VRRP Extended (VRRP-E) device enables VRRP-E to monitor the route. If the network goes down, the device priority is lowered and another backup device with a higher priority assumes the role of master.
About this task
In the following task steps, network 10.1.1.0/24 is configured to be tracked, and if the network goes offline, the VRRP priority of the current master device is lowered by a value of 20.
Procedure
-
Enable VRRP-E globally.
device(config)# protocol vrrp-extended
-
Enter interface configuration mode.
device(config)# interface ve 100
-
Run the following command to enter group configuration mode.
device(config-if-Ve-100)# vrrp-extended-group 1
-
Enter the
track network command to set the track network (route) and priority:
device(config-vrrp-group-1)# track network 10.1.1.0/24 priority 20
-
Return to privileged EXEC mode.
device(config-vrrp-group-1)# end
-
To view tracked networks with their priority and status, enter the following command:
device# show vrrp detail

Example
The following example shows how to configure network 10.1.1.0/24 to be tracked. If the network goes down, the VRRP-E device priority is lowered by a value of 20. The lower priority may trigger a switchover and a backup device with a higher priority becomes the new master for VRRP-E group 1.
device(config)# protocol vrrp-extended
device(config)# interface ve 100
device(config-if-Ve-100)# vrrp-extended-group 1
device(config-vrrp-group-1)# track network 10.1.1.0/24 priority 20
