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.

Hi Jon,

Didnt get u.

In my scenario if DC & DR both have different IP pool then I in customer VRF (in MPLS VPN cloud) both IP pool will become available and spoke location can access both DC & DR simultaneously which I do not want.

I want client to only able to access DR if DC fails.

Hi Giuseppe,

Can I use BGP conditional advertising feature in MP-IBGP instead of eBGP. i.e. if particular route present in end A PE router VRF then do not advertise alternate route to end B PE router something like this...
