Yes, this is called Multigroup HSRP (MHSRP). Basically you
would just configure a different group number for each instance of HSRP
that you want to run. In your case, you would want one per subnet, such
as the following:
!
interface FastEthernet0/0
ip address 1.0.0.1 255.0.0.0
ip address 2.0.0.1 255.0.0.0 secondary
ip address 3.0.0.1 255.0.0.0 secondary
standby 1 ip 1.0.0.254
standby 2 ip 2.0.0.254
standby 3 ip 3.0.0.254
!
You can also run multiple groups per subnet, which is
advantageous when you want some hosts on a subnet to default to 1
router, while other hosts on that same subnet are defaulting to a
different router. That config would be as follows:
R1#
interface FastEthernet0/0
ip address 1.0.0.1 255.0.0.0
standby 1 ip 1.0.0.101
standby 1 priority 110
standby 2 ip 1.0.0.102
!
R2#
interface FastEthernet1/0
ip address 1.0.0.2 255.0.0.0
standby 1 ip 1.0.0.101
standby 2 priority 110
standby 2 ip 1.0.0.102
!
