The Advanced tab controls the timers, Dynamic Host Configuration Protocol (DHCP) and Domain
Name System (DNS) options, the default route, filters, and Static Routes.
In most cases, you should not have to change any of the timers (i.e., default TTL, reassembly
timeout, RIP response time and RIP route aging time). The DNS Resolver is supplied for remote
Telnet clients when the router is configured for remote access and the terminal server application is
enabled.
The Routing option is normally checked; however, if you do not wish to have IP packets routed, then
uncheck this item. If IP routing is disabled and bridging is enabled, IP packets are bridged; i.e., IP
packets are transferred.
The RIP option enables RIP based routing. RIP (Routing Information Protocol) is a protocol used
among routers to exchange routing table information. RIP is the most common protocol used in both
IP and IPX networks. It is also used internally by client workstations in IPX networks to obtain routes
(shortest, or otherwise) to any distant network. RIP based routing should normally be enabled. It can
be disabled, however, if you are using WAN links in Dial on Demand mode. For DOD links, disabling
RIP will reduce traffic on the link as it will also disable periodic RIP broadcasts. RIP routing on a given
port will be automatically turned off when Dial on Demand is enabled on the PPP Port Setup tab for
the WAN port.
The Dynamic Host Configuration Protocol (DHCP) group enables you to set up the WAN ports as
client-only. Then, a PPP client connected to the WAN port will be on the same IP network as the LAN
port of the DSU RouteFinder. This feature can save some extra IP addresses that otherwise would
have been taken up by the WAN port. Enabling the Client option allows the DSU RouteFinder to
dynamically get an IP address for a PPP client coming up on one of its “Client-only” WAN ports. When
this option is enabled, there must be a DHCP server or a DHCP relay agent on the connected LAN in
order for the DSU RouteFinder to acquire an appropriate IP address.
The IP Advanced tab’s dialog box controls the timers, DHCP (dynamic Host Configuration Protocol)
and Domain Name System (DNS) servers, the default route, filters, and Static Routes.
In most cases, you should not have to change any of the timers (i.e., default TTL, reassembly timeout,
RIP response time and RIP route aging time). The DNS Resolver is supplied for remote Telnet clients
when the router is configured for remote access and the terminal server application is enabled.
A brief description of OSPF is provided in the following section. For more details on filtering, refer to
the Filtering section of this chapter. For details on other parameters, refer to the online help provided
with your RouteFinder software.
