Hopefully I am wording this decent enough to understand. I am working in a team where we are deploying VMware for a business that has two locations that are connected via a point-to-point wan connection. At each end of that connection they have Cisco Routers. We are virtualizing servers on both ends and using VMware to do Data Replication and keep a copy of each network on each other's server. If both networks on on two seperate subnets and they are being copied over to another VMware machine, where it will be operating side-by-side with the other network (in case of downtime at either site) can I keep things going on the networking side using the routers and EIGRP? My thought is having the disabled copies of the opposite network sitting in the VMware machine disabled, but connected physically to another ethernet interface on the local router (and the same on the other side). When the WAN link goes down, the router switches from routing to serial interface to ethernet interface #2. Is this correct? Thank You.
