Prestige 480 Dual BRI ISDN Router
Internet Access 3-3
3.3.2 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing information with other routers. The
RIP Direction field controls the sending and receiving of RIP packets. When set to Both, the Prestige will
broadcast its routing table periodically and incorporate the RIP information that it receives; when set to
None, it will not send any RIP packets and will ignore any RIP packets received.
The Version field controls the format and the broadcasting method of the RIP packets that the Prestige sends
(it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more
information. RIP-1 is probably adequate for most networks, unless you have a unusual network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses
subnet broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load on non-router
machines since they generally do not listen to the RIP multicast address and so will not receive the RIP
packets. However, if one router uses multicasting, then all routers on your network must use multicasting,
also.
By default, RIP direction is set to Both and the Version set to RIP-1.
3.3.3 DHCP Configuration
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (workstations) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP Server
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS
servers to Windows 95, Windows NT and other systems that support the DHCP client. Your Prestige can also
be configured as a Relay. When configured as a relay, the Prestige relays the requests and responses between
the clients and the real DHCP server.
IP Pool Setup
The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64.
This configuration leaves 31 IP addresses (excluding the Prestige itself) in the lower range for other server
machines, e.g., server for mail, FTP, telnet, web, etc., that you may have.
