Cabletron Systems CSX1000, CSX1200 manual IP RIP Over Dedicated Connections

USER’S GUIDE

Currently, IP RIP is not supported across an UnNumbered WAN interface. For example, in the following network setup, SITE1 could not advertise IP RIP information across the UnNumbered WAN IP Interface to Router 2 (R2). Therefore, SITE1 would know about Networks 1 and 2, but would not learn anything about Network 3. In this situation, a static route would have to be configured on the CyberSWITCH. For information on the configuration of static routes, refer to Static Routes.

i/f 1 1.0.0.1

i/f 2 2.0.0.1 Network 2 (2.0.0.0)

IP RIP OVER DEDICATED CONNECTIONS

IP RIP is supported over LAN, Remote LAN, and numbered WAN interfaces. When devices are connected over WAN links in which cost is not a major concern, such as dedicated links and semi- permanent connections, RIP can be used to provide dynamic IP routing capability, as illustrated in the following example:

Because each IP WAN network interface on the CyberSWITCH is configured for a logical IP network, various types of physical interfaces (such as V.35 and ISDN BRI) may belong to the same IP network interface. To avoid sending broadcast packets to all remote devices on an IP network, you explicitly specify with which device (only one) the system should exchange RIP packets.
