    Aggregating 2 Lines for failover / load balancing

    We have 2 campuses, linked with a dual 10gig fiber going from Core to Core on each campus. Our internet fiber comes to one campus, to an ISP provided cisco router, which is then filtered/firewalled with our device.

    We have just had a second internet fiber connection installed onto the other campus, and the ISp are putting in another cisco router.

    What we want to achieve, is to have each campus use its own connection for internet, but also allow for the other campus to use each others internet if the bandwidth gets full on one side, or if the internet goes down on either side. We also only have 1 firewall unit, and want both connections filtered. The ISP have offered us 4U in their datacenter where our fibers terminates (I think) which they have suggested we put the firewall, which will filter both connections..

    My question is, how do we configure our local network to do the bandwith utilisation if one side is saturated it uses the other, and how do we set them up to do automatic failover if one link goes down. Do we need some sort of hardware load balancer in place somewhere or .. ?

    Hope this makes sense and someone can offer some suggestions. Cheers

    There's probably a better way of doing it, but you could have your DHCP server dish out different gateway details if the first gateway got overloaded - rather a crude way of load balancing, but it would be free.
