Multipe internet access links with PAT

Hi experts,

I have two links to the access the internet one must be the primary, while
the other should be a back up upon RTR failure of the primary.

Here the configuration

interface FastEthernet0/0

 ip address 62.90.200.226 255.255.255.248

 ip nat outside

! The primary interface that face the internet

interface Dialer1

 ip nat outside

! The second backup interface that face the internet

interface FastEthernet0/1

 ip address 192.168.2.1 255.255.255.0

 ip nat inside

! The inside interface

ip nat inside source list 10 interface Dialer1 overload

ip nat inside source list 20 interface FastEthernet0/0 overload

access-list 10 permit 192.168.2.0 0.0.0.255

access-list 10 permit 192.168.2.0 0.0.0.255

ip route 0.0.0.0 0.0.0.0 62.90.200.225 50 track 1

ip route 0.0.0.0 0.0.0.0 Dialer1 51

ip sla monitor 1

 type echo protocol ipIcmpEcho 62.90.200.225 source-interface
FastEthernet0/0

 timeout 3000

ip sla monitor schedule 1 life forever start-time now

The routing table switch upon the RTR failure, but the PATing is not
switched to the backup interface?

Any help or advice?

Regards,

Amin
