Hi,

if you're not running any IGP then just  create a floating static route for the backup link( with an AD > 1 and < 255).

Hi Raja

depends on what you want to realize.

May Be you have a look into route-map based nat, with this you can realize connectivity with dual isps.

for dual interface with nat

after you sort out your routing using either IGP or static route

you need to consider using a route map with each nat command to address the exist interface as described in the document below / nat section
