LABEL DESCRIPTION
DNS Servers
First DNS Server
Second DNS Server
Third DNS Server
Select From ISP if your ISP dynamically assigns DNS server information (and
the Prestige's WAN IP address). The field to the right displays the (read-only)
DNS server IP address that the ISP assigns.
Select User-Defined if 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-Defined changes to None after
you click Apply. If you set a second choice to User-Defined, and enter the
same IP address, the second User-Defined changes 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-1 is 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-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.
