5.2.1 - Dynamic Routing Protocols in Networking

These flashcards cover key terms and concepts related to dynamic routing protocols, their operation, and classifications.

Dynamic Routing Protocol

A protocol that uses an algorithm and metrics to build and maintain a routing information base.

Routing Information Base (RIB)

A database that stores information about the networks to which a router is connected.

Learned Route

A route that was communicated to a router by another router.

Convergence

The process by which routers agree on the network topology after changes occur.

Blackhole

A condition where a packet is discarded without notification back to the source.

Loop

A situation where a packet is forwarded repeatedly around the network until its TTL expires.

Steady State

A network condition where all routers share the same topology.

Flapping Interface

An interface that frequently changes states between online and offline.

Distance Vector Protocol

A routing protocol that uses the number of hops as the metric to determine the best path.

Interior Gateway Protocol (IGP)

A routing protocol that identifies routes within a single autonomous system.

Exterior Gateway Protocol (EGP)

A routing protocol that can advertise routes between different autonomous systems.

Autonomous System (AS)

A network under the administrative control of a single owner.
