- [Instructor] It's important that we understand…administrative distances and the…three different kinds of routing protocols.…But let's start with understanding…the routing protocols using with the CCENT…and the protocols used within our IGPs for the CCENT…are RIP version two, enhanced IGRP,…and open shortest path first.…Let's make sure we have a fundamental understanding…of the difference between classful and classless.…Classful routing protocols, for example…RIP version one and then old IGRP…which isn't even supported,…don't include the subnet mask information…with the route advertisements.…
Classless routing protocols include the subnet mask…with the route advertisements and allow us…to do things like VLSM.…And these are RIP version two,…EIGRP, OSPF, and another routing protocol…not covered is the IS-IS.…So it's important to understand administrative distance…or trustworthiness of a routing protocol.…The administrative distance is used…to rate the trustworthiness of routing information…received on a router from a neighbor router.…
