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.
