IS 3800 cisco router support the HSRP using Two groups.

If yes ,pl share some configuration

Yes - it can.

Do you want 2 groups on the same interface or seperate interfaces?

If it is separate interface with two router,what would be the sample configuration?

I would have something like:-

Router 1

Interface fastethernet 0/1

ip address 172.16.1.253

standby 1 ip address 172.16.1.254

standby 1 timers 1 3

standby 1 priority 200

standby 1 preempt

Router 2

interface fastethernet 0/1

ip address 172.16.1.252

standby 1 ip address 172.16.1.254

standby 1 timers 1 3

standby 1 peempt

If I have another interface on the routers that I also wanted HSRP to run on, for that specific layer 3 subnet:-

Router 1

Interface fastethernet 0/2

ip address 192.168.1.253

standby 2 ip address 192.168.1.254

standby 2 timers 1 3

standby 2 priority 200

standby 2 preempt

Router 2

interface fastethernet 0/2

ip address 192.168.1.252

standby 2 ip address 192.168.1.254

standby 2 timers 1 3

standby 2 peempt

The important config is the Group ID = the number you choose.

If you have 50 interfaces - you can have 50 HSRP groups - The IP addresses MUST match the group ID.
