RIP Routing with Windows

After adding the routing protocol, you must then define the interfaces for which this protocol is valid. This might be a permanent interface such as with Local Areas Connections, or it might be demand-initiated connections such as dial-up connections or VPN tunnels.

The configuration of the interface is handled by accessing its properties after it has been added. For any RIP interface, there are 4 configuration tabs, including General, Security, Neighbors, and Advanced.

The General tab allows you to control the incoming and outgoing packet protocol allowed, an authentication string (only valid for version 2), as well as an operation mode, where ‘Periodic update’ is the default (another option, Auto-static mode, will be discussed in the next article). The Security tab allows you to control actions for both incoming and outgoing routes, specifically ranges that should be accepted or declined on this interface. This gives you a more granular level of control over which networks this router knows about.

The Neighbors tab allows you to control how this router interacts with other routers on the network. For example, you can specify that broadcasts or multicast get used (as they do by default), or you can add the specific IP addresses of other routers with whom information should be shared via unicast traffic. Although this may seem to be a great deal of work, it may also be a good idea from a security perspective, especially if you are worried about rogue RIP routers being created on your network and interfering with your routing infrastructure.

Finally, the Advanced tab allows you to control advanced RIP properties, including whether routes to individual hosts can be included in the announcement (they are not by default), intervals for announcements and route expiry (30 seconds and 180 seconds respectively by default) as well as other advanced RIP properties. While it would be worthwhile from a learning perspective to take the time go through each advanced setting individually, it is probably not necessary to know each setting in tremendous detail outside of a setup in a production environment.

As a side note, you should also recognize that if you are running NWLink, Windows 2000 can also run RIP for IPX and SAP (the Netware Service Advertising Protocol). These settings do not appear in the Routing and Remote Access interface until at least one interface is running IPX.
