I have a basic requirement in my network. I have 2 ISPs connected to Cisco Router. NAT is configured with per destination load balancing.
My customer wants when he access site www.abc.com It should always prefer ISP-1 and when ISP-1 is down, only then it should go to ISP-2.
The catch is I donot have any information on the IP address of www.abc.com & since the IP will be changing it is not feasible to determine the IP address too and configure manually using POLICY ROUTE-MAP.
My understanding is I can match only IP address inside the route-map & apply it in interface using command policy route-map Command
Kindly help me how to achieve this
Thanks in advance
