Configuration Examples for HSRP
Configuration Examples for HSRP
This section provides the following configuration examples:
• Example: Configuring HSRP Active Router
• Example: Configuring HSRP Backup Router
• Example: HSRP Text Authentication
Example: Configuring HSRP Active 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 10.10.10.21 255.255.255.0
Router(config-if)# standby 1 ip 10.10.10.20
Router(config-if)# standby 1 timers 1 4
Router(config-if)# standby 1 priority 105
Router(config-if)# standby 1 preempt delay minimum 10
Router(config-if)# standby 1 authentication cisco6
Router(config-if)# standby 1 track 1 decrement 20
Router(config-if)# end
Example: Configuring HSRP 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
standby [
group-number
] track
object-number
[decrement priority-decrement]
Example:
Router(config-if)# standby 1 track 100
decrement 20
Configures HSRP 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.
