Looking for Complete config for Cisco 1812 Dual Wan with IPSLA

Hi All

I have purchased a new Cisco 1812 dual wan router and 2 internet connections as follows.

ISP1 (FE0) (WAN)      
Static IP: 58.27.132.106
Subnet: 255.255.255.252
Gateway: 58.27.132.105
DNS 10.16.6.11, 10.16.7.12

ISP2 (FE1) (WAN)
DHCP:*.*.
Subnet: 255.255.255.0
Gateway: 192.168.15.1
DNS 192.168.15.1,

LAN (FE2) (LAN)
IP:      10.10.10.1
Subnet:      255.255.255.0
 
I have 2 wan ports
FastEthernet0
FastEthernet1
8 Switch Ports FastEthernet2 / 9
1 Vlan = Vlan1

What would be the complete configuration to enable FastEthernet2 to get an internet connection through the router from ISP1 FastEthernet0 and if it fails to get ISP2 via FastEthernet1 on the basis of internet connectivity not on the basis of network connectivity i.e. to ping www.google.com or any website or websites. I think this will required IP SLA Configuration.
I need failover configuration
LAN side should be enable with DHCP Pool (10.10.10.50---100) (50 clients)
The Router at moment is at factory default configuration with IOS 12.4.
I need complete Configuration from Step 1 to Last Step
Any help would be greatly appreciated.

Many Thanks

Your default route shouldn't specify FE0 as it's outbound interface, you should specifiy an IP address as the next hop. Tracking the IP should fix your problem. So, your route should be

ip route 0.0.0.0 0.0.0.0 "isp's ip address next hop" track 100

See if that works for you.

Dear All,
Find the attached Configuration after this the situation is as following
If both ISP are connected on FE0 and FE1 it auto switch between isp’s , I confirmed by visiting www.whatismyip.com and after 15 secs it goes to ISP 2 and comes back to ISP1. It is doing continuously. Attached is the result of ping.
Now if we unplug the cable of ISP1 from FE0 the internet works fine without any delay or switching. And continuous ping.
And if we plug back the cable of ISP1 FE0 and unplug the cable of ISP2 FE1 internet stopped working totally. No ping at all.
Please guide the error in my configuration.
Regards
Syed Talal Hassan.
