And more specifically, how does the last hop router determine the MAC address of the final destination? The MAC address itself is a flat identifier (and locator on the last hop) that can be embedded in the endpoint identifier, or the endpoint identifier can be used for a lookup to determine the MAC address. In either case, the endpoint identifier ends up being used for a local routing decision.
