Recently we had to get our last mile Internet connection upgraded. Switching to 60GHz technology gives us shorter rount-trip time and allows for higher bandwidth up to 1Gbps right now and about 2.5Gbps in the future. But being a wireless technology, some work had to be done physically on the roof of our offices building.

It took ages, however the replacement of our autonomous system border router (ASBR) is done. In addition we managed to converge our backbone L2 and L3 equipment and finally get a rid of two single points of failure (SPOF) in sequence.

I would like - if I may - to take you on a strange journey.

As a part of developing a simple UDP-based networking application for Linux where the client may communicate with the server over multiple physical network connections, we needed to programatically setup source-based routing. It seemed like a really simple task. A simple task which turned into a roller coaster ride from the heights of pure amusement to the very depths of hell itself.
