Tutorial: Filtering Routes in OSPF Part 2 » Filtering Between Areas Using area filter-list

In our last article on filtering Routes in OSPF we looked at filtering routes within an OSPF area. In this article we will be filtering routes between areas using the area filter-list command. OSPF route filtering is an important concept to be familiar with for any CCIE candidate. We will be looking at the area filter-list command first. Part 3 will then look at some of the more obtuse ways of filtering using the area range and summary-address commands. Part of being a CCIE is knowing multiple ways of configuring the same task…just in case those evil proctors decide to restrict which of those methods you can and can’t do! :)

Tutorial: OSPF Network Types and Frame Relay Part 5

In my previous tutorials we looked at the different OSPF Network types and also how they interact with each other. In this tutorial we will be looking at implementing OSPF over a partial mesh Frame-Relay network with multiple hubs and spokes. This is the last of the OSPF Network Types and Frame Relay series of articles….unless I find something cool! :)

Tutorial: Filtering Routes in OSPF Part 1 » Filtering Within An Area

In addition to knowing all the different OSPF Network Types and how they relate to Frame-Relay, a CCIE candidate must be familiar with the different methods of filtering routes in OSPF. This two part series of tutorials will focus on filtering routes in OSPF, both within an area and between areas. This tutorial will focus on filtering routes within an area using distribute-lists, access-lists and using a route-map.

NetKit - Full Network Emulation on Linux

Just found about NetKit thanks to a follower on twitter (I’m starting to love twitter!).
“Netkit has been conceived as an environment for setting up and performing networking experiments at low cost and with little effort. It allows to “create” several virtual network devices (full-fledged routers, switches, computers, etc.) that can be easily interconnected in [...]

Blog: Mock Lab 4 is the spawn of Satan!

Mock Lab 4 is the spawn of Satan! lol.

*sigh*. I know I stuffed that one up. I just finished it. Didn’t have much time to check anything. I got full connectivity, and answered most things. I think I got something fundamentally wrong in the IGP section. I got to the end, and i was utterly exhausted. I’m sure I made mistakes, but I will see how it goes.

Mock Lab 6 Analysis - RIP Summary Address and Default Routes

I ran into this strange problem while doing Mock Lab 6, and I thought it warranted an article because it highlights why the order of operations that IOS performs certain tasks is important.

Tutorial: IPv6 Tunnels Part 1 - Manual GRE & IPv6IP Tunnels

Lets face it, sooner or later we are going to move to IPv6. Probably closer to the sooner side than some of us are comfortable with. In this series of articles we will be introducing tunnels and taking a look at how they can be used as part of you migration towards IPv6. Working with IPv6 tunnels is also an important part of a CCIE candidate’s journey, so mastering them is important. In this article we will be looking at tunnelling IPv6 over IPv4 using manual tunnels specifically using GRE and IPv6 in IPv4.

Tutorial: OSPF Network Types and Frame Relay Part 4

In our previous tutorials (you can find Part 1 here, Part 2 here and Part 3 here) we looked at the different OSPF network types and how they apply to a partial mesh Frame-Relay Hub and spoke topology. In normal situations that would be enough, but this is the CCIE we are preparing for! We have to understand how the different network types work together. This is incase the proctor decides to not allow you to use certain types of OSPF networks on one interface or does not allow you to use the ip ospf network commands on others. Evil Proctors :)

Tutorial: OSPF Network Types and Frame Relay Part 3

In our previous tutorials on OSPF Network types (you can read Part 1 here, and Part 2 here), we looked at the OSPF broadcast, non-broadcast, point-to-multipoint, and point-to-multipoint non-broadcast network types. In this article we will be taking a look at the last of the ospf network types, namely point-to-point and loopback network types.

Tutorial: OSPF Network Types and Frame Relay Part 2

In our last article we looked at the Broadcast and Non-Broadcast OSPF network types. We will be continuing our OSPF Network Type series of articles by looking at Point-to-Multipoint and Point-to-Multipoint Non-Broadcast network types.

Tutorial: OSPF Network Types and Frame Relay Part 1

Knowing the OSPF Network Types and how they work with different frame relay topologies is one of those things that you should know inside out if you are attempting the CCIE lab. In this next series of articles we will be looking at the 5 OSPF network as well as how and when to use [...]
