Hello everyone!
I think that i'm really newbie and in view of that I have a problem im not able to resolve.
I have two firewall working in active/passive mode, and only one router with only L3 interfaces.
How to configure two interfaces with the same ip addrese?
I found out that there is somethink like "interface backup" and it's works but with restriction, i mean only when phisical interface go down, then the backup interface go up.
is there any way to do it?

Richard, @MHM Cisco World . Thank you for your advice. On Monday I’m going to test it. I will share with you with the result.

Hello,
you can use the same IP address on two interfaces, as long as one of them is in 'shut' (administratively down) state. An EEM script might be a better option. Post the running configuration of your router (put descriptions on the interfaces to indicate what is connected to which interface).

As @Richard Burts and @MHM Cisco World mention to do it I used Interface BDI assigned to two phisical interface on my router. It works fine. Thanks for your help.
