Overview

Border Gateway Protocol, or BGP, dynamically controls routing traffic between networks, or Autonomous Systems. Routers setup BGP peering sessions with each other and share information about what networks connect to them directly, as well as what routes they learn from other peers. This means that if two BGP peers lose their session, the network knows this and can send traffic on an alternate path to its destination. Much of the internet uses BGP to ensure traffic flows quickly and efficiently to its destination rather than relying on human intervention to manage routes.

Tools

BGP can be difficult to troubleshoot and configure. Here are some tools to help make your life easier:

Examples

Documentation and Futher reading

There quite a bit of documentation on Quagga/Zebra available.
Personal tools
Router software releases
