EIGRP… The Basics

Enhanced Interior Gateway Routing Protocol (EIGRP) is an impressive set of features for IP Routing, which converges quickly and is on par and sometimes faster than OSPF. This routing protocol requires less processing time, less memory, and less network design than compared to OSPF. What’s the catch? This protocol is Cisco proprietary, if you have […]

OSPF…What a Protocol!

For today let’s discuss a routing protocol that was being thought of in 1987 by the Internet Engineering Task Force (IETF). OSPF currently has three versions and the first version was in the 1980s when the internet was still being used for research. What is interesting about the first version of OSPF is although one […]

Link-State Protocols

Weeks ago and maybe months :), I talked about distance vector protocols and with that you probably got the feeling that when using a distance vector protocol it does not give a full network graphical representation of the entire network. Only the directly connected routes can’t remember? Check out this post Distance Vector Routing. Link state protocols are […]

Distance Vector Routing

Couple weeks ago I talked about routing protocols and in the post I mentioned two routing protocol features distance vector and link state. Although these protocols fundamentally do the same thing by getting information on remote networks they get this information in a different way. For today let’s introduce distance vector routing.

Classful vs. Classless Routing

Before the internet and general networking become popular into what it is now, there were and still are routing protocols that only do classful routing. What is classful routing? When I was talking about Dynamic Routing earlier (See the post Dynamic Routing Protocols) I mentioned there was a difference between classful routing and classless routing. So […]
