The design relies on standard static paths, fully specified paths for IPv6 environments, and summary structures to limit routing table inflation.

With localized Layer 2 domains defined, you must establish multi-subnet communication at the edge router gateways. This is achieved using a topology via explicit sub-interfaces. Multi-Subinterface Provisioning ccna-2v7.0 case study -rev b-
