DESCRIPTION

 

 

DNS Servers

 

 

 

First DNS Server

Select From ISP if your ISP dynamically assigns DNS server information (and

Second DNS Server

the Prestige's WAN IP address). The field to the right displays the (read-only)

DNS server IP address that the ISP assigns.

Third DNS Server

Select User-Definedif you have the IP address of a DNS server. Enter the

 

 

DNS server's IP address in the field to the right. If you chose User-Defined,

 

but leave the IP address set to 0.0.0.0, User-Definedchanges to None after

 

you click Apply. If you set a second choice to User-Defined, and enter the

 

same IP address, the second User-Definedchanges to None after you click

 

Apply.

 

Select None if you do not want to configure DNS servers. If you do not

 

configure a DNS server, you must know the IP address of a computer in order

 

to access it.

RIP and Multicast Setup

 

 

 

RIP Direction

RIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a router to

 

exchange routing information with other routers. The RIP Direction field

 

controls the sending and receiving of RIP packets. Select the RIP direction

 

from Both/In Only/Out Only/None. When set to Both or Out Only, the

 

Prestige will broadcast its routing table periodically. When set to Both or In

 

Only, it will 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.

 

Both is the default.

RIP Version

The RIP Version field controls the format and the broadcasting method of the

 

RIP packets that the Prestige sends (it recognizes both formats when

 

receiving). RIP-1is universally supported but RIP-2 carries more information.

 

RIP-1 is probably adequate for most networks, unless you have an unusual

 

network topology. Both RIP-2Band RIP-2Msends the routing data in RIP-2

 

format; the difference being that RIP-2Buses 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.
