Chapter33 Configuring HSRP
Configuring HSRP
Use the no standby [group-number] ip [ip-address] interface configuration command to disable HSRP.
This example shows how to activate HSRP for group 1 on a port. The IP address used by the hot standby
group is learned by using HSRP.
Note This procedure is the minimum number of steps requ ir ed to en ab le HSR P. Other configuration is
optional.
Switch# configure terminal
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# no switchport
Switch(config-if)# standby 1 ip
Switch(config-if)# end
Switch# show standby
Configuring HSRP Priority
The standby priority, standby preempt, and standby track interface configuration commands are all
used to set characteristics for finding active and standby routers and behavior regarding wh en a new
active router takes over.
When configuring HSRP priority, follow these guidelines:
•Assigning priority helps select the active and standby routers. If preemption is enab led, th e router
with the highest priority becomes the designated active router. If priorities ar e equal, th e primary IP
addresses are compared, and the higher IP address has priority.
Step4 no switchport If necessary, disable Layer 2 switching on the port to enable the Layer 3
interface.
Step5 standby [group-number] ip [ip-address
[secondary]] Create (or enable) the HSRP group using its number and virtual IP
address.
•(Optional) group-number—The group number on the interface for
which HSRP is being enabled. The range is 0 to 255; the default is 0.
If there is only one HSRP group, you do not need to enter a group
number.
•(Optional on all but one interface) ip-address—The virtual IP address
of the hot standby router interface. You must enter the virtual IP
address for at least one of the interfaces; it can be learned on the other
interfaces.
•(Optional) secondary—The IP address is a secondary hot standby
router interface. If neither router is designated as a secondary or
standby router and no priorities are set, the primary IP addresses are
compared and the higher IP address is the active router, with the next
highest as the standby router.
Step6 end Return to privileged EXEC mode.
Step7 show standby [interface-id [group]] Verify the configuration.
Step8 copy running-config startup-config (Optional) Save your entries in the configuration file.
