4.5. Securing Routing Protocols
Within a network there are probably multiple routing methods. Most large networks use a combination of static routing. It is important when selecting a routing method to fully understand the potential security holes, and to take steps to address them. This section will address static routing, as well as three very common dynamic routing protocols: RIP, BGP, and OSPF.
An in-depth explanation of the configuration process for the routing options discussed in this section is beyond the scope of this book. So, while there are some configuration examples in this chapter, they are by no means intended to be complete. Most vendor websites offer configuration examples for the different protocols listed here.
