Rajan,
You can try giving 2 static routes. One for primary link(VSAT link) and
other static route for the Dial Backup.
one static route will be for the primary link and the other static route
with higher metric(Adm. distance) will be for Dial backup.
By doing this, you don't need to make any changes in the Local Lan as well
as in the router, just you need to put one static route in the router for
dial backup with higher metric.
