You have just received a nice job at a big enterprise that has multiple sites connected over their own managed MPLS Core. Each site runs EIGRP as the CE - PE routing protocol. You get the task to route some traffic in a particular way, but you cannot make it. What is missing ?

This article discusses the solutions for quiz 14 and it describes some scenarios to help understand why redistributing iBGP into IGP (OSPF in this case) is dangerous.

Here I come with the solution for quiz-12, that I consider to be one of the most difficult quizes published on this blog, until now. Forwarding Address (FA) is not quite a common nor easy to understand topic. Read to find out more.

Your network follows a standard 3 tier hierarchical design (Core, Distribution, Access) and has two WAN circuits with eBGP sessions with the ISPs. You want to push the default route down to the Distribution routers, but something goes wrong. Where is the mistake?

This post represents the solution and explanation for quiz-10. It describes the functionality of the Down Bit in preventing routing loops in your network.

Company ABC closes a deal with a Partner Company that requires redundant network paths between the two networks. Two connections are installed between the companies, but the traffic seems to go over the slower one. Why ?

This post represents the solution and explanation for quiz-2.
It shows one of the common problems, solutions and recommendations when implementing MSTP.

Redistribution between different or same routing protocols can become a nasty thing when there are 2 or more redistribution points.
In this quiz, redistribution is configured between 2 different OSPF processes on 2 routers. Without a proper configuration, this can lead to routing loops. Read the quiz to see the loop in action and try to solve it.
