General Routing Concepts

Link-State and Distance Vector Protocols

Distance Vector

Examples: Routing Information Protocol Version 1 (RIPv1), RIPv2, Interior Gateway Routing Protocol (IGRP)

• Features periodic transmission of entire routing tables to directly connected neighbors

• Mathematically compares routes using some measurement of distance

• Features hop-count limitation

Link State

Examples: Open Shortest Path First (OSPF), Intermediate System-to-Intermediate System (IS-IS)

• Sends local connection information to all nodes in the internetwork.

• Forms adjacencies with neighboring routers that speak the same protocol; sends local link information to these devices.

• Although this floods of information ...
