Policy Based Routing Solution

Hi,

yesterday amith has suggested me to go head with PBR config, meanz i will b having 2 different ISP which will b connected to a single router(Cisco 2800),each ISP has given me public IP address, they both fall under different series(being a different ISP), now my web server is residing inside my LAN with an IP 172.1.1.1/24, internet userz will access this web server with a help of static NAT configured on my ASA 5510 with the help of abc.co.in(202.1.1.1, public IP of provided by ISP-1), which meanz whomsoever from the internet access abc.co.in, it will point to my LAN webserver 172.1.1.1, now this workz fine, but assume that if ISP-1 failz, still i wanted to access abc.co.in, which meanz automatically abc.co.in should be resolved with 203.1.1.1 public IP provided by ISP-2 to my webserver 172.1.1.1. this should be based on the priority which meanz higher priority for 202.1.1.1------>172.1.1.1 & lower priority to 203.1.1.1----->172.1.1.1. & Amith has suggested PBR-Differing Next Hops, i am bit confused with that example that which is the private IP & which is the public IP as mentioned in the example. also how do u give higher priority to 202.1.1.1 & lower to 203.1.1.1 on ASA 5510 in NATting.

Attached is the PBR document suggested by Amith.

Anand,

When you multihome its always better to have the static NATS in your own public ip pool provided either by APNIC, ARIN etc.

Not sure if how to configure priority with NAT
