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.

3.2.3 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 the DHCP server capability built-in and is enabled by default.

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.

DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa, e.g., the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it. The DNS server addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP address and subnet mask. Make sure that you obtain the IP address of the DNS servers from your ISP. Your workstations will need this information even if you don’t use the Prestige’s DHCP server.
