Network+ Module 15 - Routing Technologies

This set of flashcards includes key vocabulary terms and their definitions related to routing technologies, routing tables, routing protocols, and route selection as discussed in the lecture notes.

Routing Tables

A file that contains rules showing the path a data packet takes to its destination.

Static Routes

Routes manually entered by a network administrator.

Dynamic Routes

Routes that are entered automatically by neighboring routers.

Routing Information Protocol (RIP)

The oldest dynamic routing protocol that broadcasts information every 30 seconds.

Open Shortest Path First (OSPF)

A link-state dynamic routing protocol that uses the shortest path first algorithm.

Border Gateway Protocol (BGP)

The standard dynamic routing protocol of the internet classified as a distance vector routing protocol.

Enhanced Interior Gateway Routing Protocol (EIGRP)

A hybrid dynamic routing protocol combining distance vector and link-state protocols, using DUAL to find the best path.

Route Selection

The process by which a router selects the best path to forward data packets based on different criteria.

Administrative Distance

A value used to choose the best route when multiple routes exist for the same destination.

Metric

A numerical value indicating the 'cost' or preference of a particular path.

IPv4 Prefix Length

The bit count in the network part of an IP address, determining entries in routing tables.
