Hello

we have 2 internet lines,
The main line is a satellite and the backup line is (2xT1)
I am trying to configure IP SLA so if the main line is down it will switch to the backup automatically.
i tried the attached code:

 
ip sla 1

icmp-echo 4.2.2.1 source-ip (main interface)

frequency 5

timeout 1000

threshold 250

ip sla schedule 1 life forever start-time now



!

ip sla 2

icmp-echo 8.8.8.8 source-ip (main interface)

timeout 1000

threshold 250

ip sla schedule 2 life forever start-time after 00:00:30

!



track 1 rtr 1 reachability

track 2 rtr 2 reachability



!



track 3 list boolean or     



object 1

object 2



!

ip route 0.0.0.0 0.0.0.0 (main interface)track 3

ip route 0.0.0.0 0.0.0.0 (backup interface)100

ip route 4.2.2.1 255.255.255.255 (main interface) permanent

ip route 8.8.8.8 255.255.255.255 (main interface) permanent



!

event manager applet Main-line-down

event track 3 state down

action 1.1 cli command "en"

action 1.2 cli command "conf t"

action 1.3 cli command "int g0/0"

action 1.4 cli command "shut"

Open in new window



it works great however both conditions object 1 and 2 are failing several times a day and the backup connects. The main line is not really down, and if you run "sh track ..."  the reason code for beign down is time out.


I would appreciate the advice

Thanks

The route statements are confusing to me.
are you using next-hop ip addresses, or interface names for the route?
