[c-nsp] Best design can fit DC to DC

[Vitkovský Adam]

Hi folks, 

OTV please ... 
If you have a unique opportunity to rebuild the DCs and their interconnect you can as well do it right. 
You may really want to use a full blown standards based MPLS solution for the DCI part. 
Then you can start small with just p2p PWs and a backup peers to create L2 pipes between the DCs. 
Or you can use VPLS already to prepare for more than 2 DCs. 
Or you can use PBB-EVPN to get the best that is out there for DCI. 
 
If you want sub-sec convergence within the DC you may want to use any technology that allows you to build a link-bundle from a single access device to two upstream devices(VSS, V-PC, MC-LAG).  
Or you can get a rid of STP altogether by running L2MP like TRILL or FbricPath within the DC.
