Windows 2000 and IP Routing

An Internet Protocol (IP) router is an IP node that can forward IP packets that are not addressed to the router. Microsoft® Windows NT® version 4.0 and earlier provided a static IP router for simple IP routing. Microsoft® Windows NT® version 3.51 (Service Pack 2 and newer) and Microsoft® Windows NT® Server 4.0 provided a Routing Information Protocol (RIP) for IP service using RIP for IP version 1 (v1). The Routing and Remote Access Service (RRAS) for Windows NT 4.0 (Service Pack 3 and later) provided an integrated IP router with support for RIP for IP (v1 and v2), Open Shortest Path First (OSPF), IP packet filtering, demand-dial routing, and other features.

Windows 2000 Server provides the Routing and Remote Access service with support for RIP for IP, OSPF, IP packet filtering, demand-dial routing, and network address translation. For more information about the components in Windows 2000 that make up the IP router, see "Routing and Remote Access Service" in this book.
