Configuration Examples for VRRP

This section provides the following configuration examples:
•Example: Configuring a VRRP Master Router
•Example: Configuring a VRRP Backup Router
•Example: VRRP Text Authentication

Example: Configuring a VRRP Master Router

This example shows how to configure a VRRP Master router.

Router# configure terminal
Router(config)# interface GigabitEthernet0/1
Router(config-if)# service instance 1 ethernet
Router(config-if-srv)# encapsulation dot1q 10
Router(config-if-srv)# rewrite ingress tag pop 1 symmetric
Router(config-if-srv)# bridge-domain 10
Router(config-if-srv)# end
Router# configure terminal
Router(config)# interface Vlan10
Router(config-if)# ip address 10.10.10.25 255.255.255.0
Router(config-if)# vrrp 2 ip 10.10.10.30
Router(config-if)# vrrp 2 timers advertise 2
Router(config-if)# vrrp 2 preempt delay minimum 10
Router(config-if)# vrrp 2 priority 110
Router(config-if)# vrrp 2 authentication text cisco7
Router(config-if)# vrrp 2 track 1 decrement 20
Router(config-if)# end

Example: Configuring a VRRP Backup Router

Router# configure terminal
Router(config)# interface GigabitEthernet0/1
Router(config-if)# service instance 1 ethernet
Router(config-if-srv)# encapsulation dot1q 10
Router(config-if-srv)# rewrite ingress tag pop 1 symmetric
Router(config-if-srv)# bridge-domain 10
Router(config-if-srv)# end
Step 9 vrrp [
group-number
]
track
object-number
[decrement priority-decrement]
Example:
Router(config-if)# vrrp 2 track 1 decrement 20

Configures VRRP to track an object and change the Hot

Standby priority on the basis of the state of the object.

Step 10 end
Example:
Router(config-if)# end

Returns to privileged EXEC mode.
