8.2 HSRP Configuration
8.2.2 HSRP standby priority
Each standby group has its own active and standby routers. The network administrator can assign a priority value to each router in a standby group, allowing the administrator to control the order in which active routers for that group are selected.

To set the priority value of a router, enter the following command in interface configuration mode.

Router#(config-if)standby group-number priority priority-value

Variable  Definition
group-number  Indicates the HSRP standby group; this number is in the range of 0 to 255
Priority-value  Indicates the number that prioritizes a potential hot standby router; the range is 0 to 255; the default is 100

The router in an HSRP group with the highest priority becomes the forwarding router. The tiebreaker for matching priority is higher number IP address.

The example in the Figure to the left shows that Router-A interface FastEthernet 0/0 has a priority value of 150 in HSRP standby group 50.

Lab Activity
  In this lab activity, you will learn how to configure HSRP on a pair of routers to provide redundant router services to a network.
