WINDOWS 2000 SERVER
By default, RRAS doesn't enable Routing Information Protocol (RIP), which enables routers to share information and learn routes from adjacent routers. But Windows 2000 does support RIP versions 1 and 2, and adding RIP enables a RRAS router to discover routes automatically, eliminating the need to add static routes to the router.
To add RIP, open the RRAS console, expand the IP Routing branch of the server, right-click the General branch, and choose New Routing Protocol. Select RIP Version 2 For Internet Protocol, and click OK. You should see a new RIP branch appear under the IP Routing branch.
Next, right-click the RIP branch, and choose New Interface. Select the interface on which you want RIP to run, and click OK.
RRAS displays a property sheet that you can use to specify the version of RIP, actions the router should take for incoming and outgoing routes, and other properties. In many installations, you can use the default settings.
