I have seen this question asked before and have looked at response and checked cisco example here :
http://www.cisco.com/warp/public/619/7.html

I am left with one question relevant to a similar configuration I would like to implement. I have tow edge routers that connect to 2 seperate ISP's. They have different ip ranges and I will give an example config here : The question I have is what do I configure the standby ip's to on both routers????? The cisco example is nice and easy with ip in the same range. I want these routers both active per group settigns and priority but need 2 standby ip's on each router..

How do I do this and make this work with different ip ranges on each router??

Router 1
interface FastEthernet0/0
       ip address 216.x.x.x /29
         ip address
       ip nbar protocol-discovery
       duplex auto
        speed auto
        no cdp enable
        standby delay reload 600
        standby preempt delay minimum 600 reload
        standby 1 ip
       standby 1 preempt
        standby 1 track Serial4/0
       standby 2 ip
       standby 2 priority 95
       standby 2 preempt
       standby 2 track Serial4/0



Router 2
interface FastEthernet0/1

       ip address 65.x.x.x/29
       speed 100
       full-duplex
       standby delay reload 600
       standby preempt delay minimum 600
       standby 1 ip
       standby 1 priority 95
       standby 1 preempt
       standby 1 track FastEthernet0/0       
         standby 2 ip
       standby 2 preempt
       standby 2 FastEthernet0/

Thanks for any help

I don't think you could easily do this, because all of your routes and such would not match the ip and settings of the ISP in the failover scenerio...

You would need to do somehting like this..

http://www.cisco.com/warp/public/459/hsrp_bgp.html

you would need to work with each ISP in order to perform the BGP with your routers,  you will also need routers with significant memory as the BGP tables are quite large...

Is it possible to create secondary interface on each router and do it that way?

BGP will be configured so it  should be able to route

Yes you can accomplish this with configuring a secondary address on each of the interface on the edge routers. You then establish IBGP between the two and the routing will work with different ip ranges.
