BGP - Same IP Segments in 2 DC
I have 2 DC. I want to have the same IP Segment in both the locations.
For ex the segment is 10.10.10.0/24
Both the DC will be having this segment.
The primary servers in the primary DC will have IP 10.10.10.1
The secondary servers in the backup DC will also have IP 10.10.10.2
In case my primary server is down the users will be able to access the server in backup DC with out changing the IP Address.
Let me know can this be achieved via BGP as routing protocol.
Let me know how to achieve this.

You can simply do HSRP..I am giving you an example
Primary DC LAN interface
interface <<LAN>>
description primary DC LAN
ip address 10.10.10.1 255.255.255.0
no ip proxy-arp
standby 0 ip 10.10.10.3
standby 0 priority 200
standby 0 preempt
standby 0 track <<Primary DC WAN interface>> decrement 20
no shut
Secondary DC LAN interface
!
interface <<LAN>>
description Secandary DC LAN
ip address 10.10.10.2 255.255.255.0
standby 0 ip 10.10.10.3
standby 0 preempt
no snmp trap link-status
no shut
!
note: I took 10.10.10.3 as HSRP IP. You can take any IP from same subnet as HSRP IP but do not use it anywhere else.
