In VPN n/w i have DC & DR. Both DC & DR r geographically separate. Server IP pool used both in DC & DR is different. Need to configure MPLS VPN in such way that when DC is active spoke should not able to access DR. when DC becomes unvailable spoke shoould able to access DR.
I m thinkin of conditional BGP. Let me know if you have any suggestion on conditional BGP or different solution.
