I have two ISPs connected to our network. Each with a T-1 connected to a separate router. Each router then is pointed to a separate web server, which gives us server redundancy. I have an online ordering system that requires inbound access to eitherone of our web servers. Presently, ordering customers access the first website, then if it is down they go to the second website. This gives us inbound redundancy but I would like to make the process transparent to the customer. I would like to configure our connection to fail over to the second router if the 1st ISP goes down.
It seems that if you could do 2 DNS A-records with different path cost, it would work, but I don?t think you can have two A-records. BGP is an option but seems to bethe most cumbersome way to handle this, but maybe the only way. I have also been suggested a possible round robin DNS solution, or Radware?s LinkProof box.
Any suggestions on how to best to handle this inbound redundancy setup would be greatly appreciated.
