[c-nsp] R: Re: Best design can fit DC to DC

[Andrew Miehs]

I didnt mention stp.

I still dont think l2 between dcs is a good idea - stp separation or not.

Otv would probably provide the separation that you want.

I assume you are only running ethernet circuits for wan so i would still use 6800s or n7ks - and these are the only cisco ones you could use to run mpls.

Will you be using vmware? Nsx may be a good solution for this - and use nsx to provide the overlay network.

You could then use n56k or n6ks with n2ks for the client ports which would bring the price down.

There was a packet pushers episode where the described the avaya solution used for the winter olympics - http://packetpushers.net/show-179-avaya-efficient-data-center-design-at-fujitsu-the-olympics-sponsored/

The juniper qfx5100s look like the cheapest bang for buck solution at the moment - and can run mpls....

Good luck and lots of reading!
