Implement HSRP

Gateway Redundancy

Goal

Configure HSRPv2 so R1 is the active gateway by default, R2 takes over if R1's uplink fails, then verify failover.

Implement HSRP

Configure HSRPv2 so R1 is the active gateway by default, R2 takes over if R1's uplink fails, then verify failover.

Gateway Redundancy

R1#
interface g0/0/0
 no shutdown
 ip address 192.168.1.2 255.255.255.0     ! R2 uses .3
interface g0/0/1
 no shutdown
 ip address 10.0.0.2 255.255.255.0       ! R2 uses .3

Standard Addressing (template — use YOUR lab table)

R1#
interface g0/0/0
 standby version 2
 standby 1 ip 192.168.1.1
 standby 1 priority 150
 standby 1 preempt
 standby 1 track interface g0/0/1 decrement 20

VLAN LAN: 192.168.1.0/24, virtual gateway IP 192.168.1.1. R1 G0/0/0 = 192.168.1.2 ; R2 G0/0/0 = 192.168.1.3. R1 G0/0/1 = 10.0.0.2 / R2 G0/0/1 = 10.0.0.3 (tracked uplinks) → 10.0.0.1 upstream. Host PC: 192.168.1.10, gateway 192.168.1.1.

Priority stays at default 100, so R1 wins while its tracked uplink is up.
