Currently we have DC-1 running
eBGP with my ISP using AS:1111 and i have prefix 220.127.116.11/24 and using
BGP Default route because we have only single ISP.
Now we are opening new Datacenter in remote geolocation and we don't have any dedicated WAN link between datacenter, and same ISP going to provide us Internet connectivity with BGP default route.
- Do i need to get new AS number for new DC-2 ?
- If i want to use same AS number then what BGP will understand (or it's impossible to use same AS on two location?)
- what are the best practice people do in this scenario?
