Dear.
I have a query regarding fabric path and its operation in a specific topology (attached file).
They are 4 Nexus, which are separated into two pairs each linked with two links, in addition each pair has VPC +. The servers are connected to the same nexus and between the two pairs is enabled Fabric path. At the Fabric path topology level, the Nexus are Leaf because they have fabric path and classic Ethernet connections, the access and distribution layer are together. Is there a problem if I have not marked the leaf - spine architecture ?, in this case there is no spine, since the layers are together. (See diagram attached).
Another doubt, the links between the nexus pair must be L2 (be able to pass vlan through the links), since if they were L3 (router between links) the fabric path would not make any sense, is it?
