Configuring HSRP on an Interface

interface Ethernet2/1 ip address 192.168.10.2 255.255.255.0 standby 0 ip 192.168.10.1	interface Ethernet2/1 ip address 192.168.10.2/24 hsrp 0 ip 192.168.10.1

Configuring the priority and preempt Options

interface Ethernet2/1 ip address 192.168.10.2 255.255.255.0 standby 0 ip 192.168.10.1 standby 0 priority 110 standby 0 preempt	interface Ethernet2/1 ip address 192.168.10.2/24 hsrp 0 preempt priority 110 ip 192.168.10.1

Modifying the Hello and Holdtime Timers (Milliseconds)

interface Ethernet2/1 ip address 192.168.10.2 255.255.255.0 standby 0 ip 192.168.10.1 standby 0 timers msec 250 msec 750	interface Ethernet2/1 ip address 192.168.10.2/24 hsrp 0 timers msec 250 msec 750 ip 192.168.10.1

Configuring MD5 Authentication

interface Ethernet2/1 ip address 192.168.10.2 255.255.255.0 standby 0 ip 192.168.10.1 standby 0 authentication md5 key-string cisco123	interface Ethernet2/1 ip address 192.168.10.2/24 hsrp 0 authentication md5 key-string cisco123 ip 192.168.10.1

Configuring HSRP Version 2 on an Interface

interface Ethernet2/1 ip address 192.168.10.2 255.255.255.0 standby version 2	interface Ethernet2/1 ip address 192.168.10.2/24 hsrp version 2

Configuring Minimum and Reload Initialization Delay

interface Ethernet2/1 ip address 192.168.10.2 255.255.255.0 standby delay minimum 5 reload 10	interface Ethernet2/1 ip address 192.168.10.2/24 hsrp delay minimum 5 reload 10

Configuring Object Tracking (Interface Line-Protocol)

track 1 interface Ethernet2/2 line-protocol interface Ethernet2/1 ip address 192.168.10.2 255.255.255.0 standby 0 ip 192.168.10.1 standby 0 track 1 decrement 20	track 1 interface ethernet 2/2 line-protocol interface Ethernet2/1 ip address 192.168.10.2/24 hsrp 0 track 1 decrement 20 ip 192.168.10.1
