Hi,
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.
Hi,
Genrally it depends on the resource and capacity of the DR infrastructure,Like if DC is having 3 server to tackle the user load and DR is having only one then best way is to have active/passive method making DC as active and DR in passive.
If at all you want to utilse the DR infrastructer you can us that also with help of DNS load balancing like publishing the webser to your root dns by making A record of the webserver with both the DC and DR isp public address.In this case both DC and DR will be running in active and active mode in round robin fashion.
Hope to Help !!
