Classful Routing Overview

–Classful routing protocols do not include the subnet mask with the route advertisement.

–Within the same network, consistency of the subnet masks is assumed.

–Summary routes are exchanged between foreign networks.

–Examples of classful routing protocols:• RIP Version 1 (RIPv1)• IGRP

Classless Routing Overview– Classless routing protocols include the subnet

mask with the route advertisement.

– Classless routing protocols support variable-length subnet masking (VLSM).

– Summary routes can be manually controlled within the network.

– Examples of classless routing protocols:• RIP Version 2 (RIPv2)

• EIGRP

• OSPF

• IS-IS
