Configuring Router redundancy with HSRP

To configure HSRP on a network there must be at least two edge routers facing the WAN. It is also advised that all ip addresses are assined to network devices to avoid error.

R1 configuration - Primary router

R1(config)# int g0/0
R1(config-if)# standby 1 ip 192.168.1.1

Configuring priority:

R1(config-if)# standby 1 priority 150
R1(config-if)# standby 1 preempt

R2 configuration - Backup routers

R2(config)# int g0/0
R2(config-if)# standby 1 ip 192.168.1.1
