Appendix D. Routing Protocols

The distribution of routing information is a fundamental part of the operation of large TCP/IP networks. On most networks, Windows NT systems are not used as routers and do not participate in the routing protocols. Usually this task is handled by dedicated IP router hardware. However, as described in Chapter 9, it is possible to use a Windows NT system as a router, and it is always important for a TCP/IP network administrator to understand routing. This appendix covers some of the TCP/IP routing protocols, which are a complex technical subject. It is unlikely you will need this information to configure an NT system, but it may come in handy if you are ever called upon to configure your network’s router or if you use a Windows NT system for routing.

Routing protocols are divided into two general groups depending on whether the protocol is used to distribute routing information isnside of or between autonomous systems (AS). An autonomous system is a collection of networks and gateways with an internal mechanism for collecting routing information and a mechanism for passing it to other independent network systems. Within an autonomous system, routing information is exchanged using an interior routing protocol. The routing information is passed to the other network systems using an exterior routing protocol. If you run a routing protocol on your NT system it will probably be an interior routing protocol.
