IOS Noob here, load-balancing and/or fail over configuration

[BledarShehu]

Hello There,

Firstly a brief introduction of what i have:

A cisco 1941 Router + HWIC-2FE

2 Static IP Incoming Lines (Both of them 5mb UP/Down)

Now i have seen all over the forums what i could find , and i have setup a SLA fail over, but for some reason it alaways gives problem , if anoyone is kind enough to have time and some solution at least for fail over and not for Load-Balancing , it would be really appriciated .

Thanks for your time

This should help:

considering gig0/0 connects to 1st isp and gig0/1 connects to 2nd isp

ip route 4.2.2.2 255.255.255.255 <1st isp gateway> permanent

track1 ip route 4.2.2.2 reachability

ip route 0.0.0.0 0.0.0.0 <1st isp gateway> track 1
ip route 0.0.0.0 0.0.0.0 <2nd isp gateway> 10

ip nat inside source route-map ISP1 gig0/0 overload
ip nat inside roure route-map ISP2 gig0/1overload

route-map ISP1
match interface gig0/0

route-map ISP2
match int gig0/1
