Hi,
I have got a customer request to build a greenfield 2 sites DCI using BGW back to back model, with 2 x N9K at each site. There is no other spine nor leaf purchased for this project so the 2 BGWs at each site will act as the leaf role. In this scenario, is it supported for BGW/Spine/Leaf all aggregated into one switch?
With that design, I also would assume vPC will need to run from BGW/Spine/Leaf towards to end hosts (running LACP). Is that a valid design? I have read through the multisite design guide looks like this design falls into the legacy integration piece?
The customer also requires these configurations to be managed by NDFC, so what role should I set for the BGW/Spine/Leaf? Would BGW Spine be enough?
What about L4-L7 integration with firewall? The customer has a pair of cross-site Palo Alto firewall in place so that will need to be transitioned to this new DCI too.
Thanks.
