Hello Gajanan,


reliable static routing with object tracking can help in your scenario:

you can trace ip reachability of an ip address in provider1 for example.

When the test fails the backup route is used

Hope to help

Giuseppe

You have not included in the post the configuration of the static routes. So we can not tell whether you have actually included the track option in the configuration of the primary static route. The track option in the static route detects when the address you are tracking is not available and at that point the static route is removed from the routing table. So have you included the track option in the static route?
