A specific static route to a remote loopback is the simplest possible deterministic routing test. The loopback as the ping

By default, OSPF neighbors will form an adjacency with anyone speaking the protocol on the same segment. In a production

EIGRP's signature feature is sub-second convergence on common failure modes. The secret: DUAL (Diffusing Update Algorithm) precomputes loop-free

EIGRP (Enhanced Interior Gateway Routing Protocol) is Cisco's dynamic routing protocol. It uses the DUAL algorithm (Diffusing Update

Multi-area OSPF divides a network into smaller logical zones connected through Area 0 (the backbone). Each non-backbone area connects to

RIP (Routing Information Protocol) is the dynamic routing protocol every textbook teaches first because it is the simplest. Distance-vector, hop
