Jarrett,

You can use secondary IP's in HSRP too. See below for an example.

Router A

interface Vlan1

ip address 10.0.2.2 255.255.255.0 secondary

ip address 10.0.1.1 255.255.255.0

Router B

interface vlan1

ip address 10.0.2.3 255.255.255.0 secondary

ip address 10.0.1.3 255.255.255.0

HSRP commands

standby 1 ip 10.0.1.1

standby 1 ip 10.0.2.1 secondary

standby 1 preempt

standby 1 priority 130

Hope this helps!

Mark
