Hi, There''s some very silly mistake i''ve done in my configuration. I did by reading material on web. I''m enclosing my configuration script below. The problem is its not routing the trafic from other interface in case the first interface is down....which should be the wright case. Kindly please guide me what i can do to make it work..dynamically..
