We look at the Border Gateway Protocol, how it routes packets through the Internet, its weaknesses, and some hardening strategies.

The FRR open routing stack can be integrated into many networks because it supports a large number of routing protocols, though its strong dependence on the underlying kernel means it requires some manual configuration.

A close look at the network traffic on a server with the bandwhich and iftop utilities can reveal exactly why an application is behaving strangely.

Large environments such as clouds pose demands on the network, some of which cannot be met with Layer 2 solutions. The Border Gateway Protocol jumps into the breach in Layer 3 and ensures seamlessly scalable networks.
