Internal Routing Protocols
Dynamic routing, after all, is what sets IP apart from its circuit-switched cousins in the telco world. Within an administrative domain (an organization, campus, or any entity that has control over a "single" network) there are a few options available when the time comes to deploy a routing protocol.
Until the mid-1990s, the no-brain choice for internal routing was RIP. Its main attraction? It was, and it remains, extremely easy to configure. It's still out there, and not just in legacy installations, but the list of factors that make it less than optimal for use on the Internet at large has grown over time. For one, RIP was designed for a classful world. This is the reason most frequently trotted out by rabid anti-RIP fanatics like, well, us, but it's also the least convincing—classless routing was retrofitted, along with a bunch of other stuff, into RIPv2.[6]
Much as we would like to dispense with it, RIP is still around in the IPv6 world, and we deal with it in more detail in Section 1.7 in Chapter 3 and the Section 6.3.3 in Chapter 6. Thankfully, there are much better internal routing protocols available these days[7]—ones which do not limit the ...
