1. We have a production server farm using a /24 public address. In a failover event the /24 pool gets advertised via BGP and fails over to a DR site. The issue we have is the DR site is only accessible during failover mode. What is best practice for this?
2. We have a internal fibre WAN connection directly to the DR site. MY question is what is the best design for this scenario? I want to improve the way the Production server farm can connect to the DR server farm using same IP ranges. Will VRF-lite router work with one-to-nat work? If so where would I need to place the router.
