Does anybody have a GOOD document that discusses policy based routing in a data center -- or better yet, between 2 data centers. A document that will cover methods and cosiderations for things like Internet access failover between 2 data centers, backhauling traffic for SAN replication and backup, running an Active/Active routing methodology for data centers, etc.
In short, a document that specifically discusses - in depth - ROUTING in a data center(s).
Some good links will be greatly appreciated. I've done some research, but I bet there's stuff I am unaware of.
