I have two campuses, each with their own 100Mbps Internet connection, that I would like to configure for Internet redundancy.
My current setup consist of a split class C address block where we route addresses 184.108.40.206 - .128 to campus A and addresses 220.127.116.11-.254 to campus B.
I am wanting to do an active/active type configuration so that both connections can be equally utilized during normal operating conditions, so that failover is in place during an outage at one campus. Do note that I am using the same ISP for both connections. I am thinking that I'll need (2) ASA5520's to do this. What I'm a little uncertain of is how I need to configure the equipment behind the firewall to support this type of configuation.
Do note that I am open to any other suggestions in regards to my redundant Internet solution. Any ideas would be great.
