Hello,
I had to move my whole network from DC1 to DC2.
I have my ASN, and I am advertising my 10.20.30.0/22 network with BGP at DC1. Mostly I am using 10.20.30.0/24 network for all devices. I am using Mikrotiks for routing.
What I already did:
I set up router 10.20.30.2/24 in DC2 with EoIP tunnel connecting to edge router in DC1 10.20.30.1/24
The tunnel worked properly, so I moved all my servers and routers to DC2, but the edge router.
All worked well, so I want to remove edge router from DC1 now. Is there a way to do this without any downtime?
I thought I should now set up second BGP session and advertise my ASN from DC2.
Then route all egress traffic through my router in DC2.
Is there anything I can do to route smoothly ingress traffic to DC2, so I can remove router in DC1 without complications?
