Hi Dears. This is my configuration. I configurated HSRP between 2 router. HSRP tracked outside interface and all of them is ok.
i have 2 ISP and this configurate on subinterface. I want to 192.168.10.0 NAT to ISP1(PAT) and 192.168.100.0 NAT to ISP2(PAT) at the same time.
if the ISP1 is down the 192.168.10.0 go to ISP2 and if the ISP2 is down the 192.168.100.0 NAT to ISP1.
i configurate that way but how I do the nat on redundancy?

ip nat inside source route-map ISP1 interface GigabitEthernet0/0.105 overload ---- this is my nat, this nat is work but i want the how do the redundancy nat?
