However, in the absence of a next-hop IP address on a multi-access segment, route leaking becomes tricky as you cannot use static route.

To leak routes between different VRFs across VTEPs, use route-target export and route-target import commands under the vrf context configuration section.

The same applies for the return traffic. For this design, the "centralized" concept is not fulfilled. Note : Be aware of CSCvn Just like in the previous scenario, use route-target export and route-target import commands under both vrf context configuration sections to leak the routes between the VRFs.
