Hi,

You can use Back to Back VPC, see the following example:

Hi,

I would say it heavily depends on the requirements to the DR site and the switch models (line cards)? Are there a requirement for L2 between the sites or will L3 be just fine? I would always try go with L3 routing between sites to avoid L2 loops. If L2 is a requirement, then back-to-back VPC as Malik suggest will be a fine way to go.
