USER’S GUIDE
120 CyberSWITCH
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 .
IP RIP OVER D EDICATED C ONNECTIONS
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.
