Layer 2 bridging between layer 3 nodes

What is the best method to extend a provider subnet (/29) from the edge CE router (ISR4331), to another layer 3 device when the two nodes are separated by a layer 2 switch? I.e. I want the edge router, the second layer 3 node and the provider’s PE edge device to all be part of the same public IP subnet. Is BDI or EVC the answer?
