You want to load-balance your traffic between two (or more) HSRP routers.
You can configure HSRP so that both routers are always in use if they are available. This allows you to use your network resources more efficiently, but it is slightly more complicated to configure.
Configure the first router as follows, with two HSRP groups:
Router1#configure terminalEnter configuration commands, one per line. End with CNTL/Z. Router1(config)#interfaceRouter1(config-if)#FastEthernet0/1ip addressRouter1(config-if)#172.22.1.3 255.255.255.0standby 1 ipRouter1(config-if)#172.22.1.1standby 1 priority 120Router1(config-if)#standby 1 preemptRouter1(config-if)#standby 2 ipRouter1(config-if)#172.22.1.2standby 2 priority 110Router1(config-if)#standby 2 preemptRouter1(config-if)#exitRouter1(config)#endRouter1#
Then, on the second router, you create the same two HSRP groups,
but change the priority levels from those of the first router so that
Router1 is active for group 1 and
Router2 is active for group
2:
Router2#configure terminalEnter configuration commands, one per line. End with CNTL/Z. Router2(config)#interfaceRouter2(config-if)#FastEthernet1/0ip addressRouter2(config-if)#172.22.1.4 255.255.255.0standby 1 ipRouter2(config-if)#172.22.1.1standby 1 priority 110Router2(config-if)#standby 1 preemptRouter2(config-if)#standby 2 ipRouter2(config-if)#172.22.1.2standby 2 priority 120Router2(config-if)#standby 2 preemptRouter2(config-if)#exit ...
