The Advanced tab controls the timers, Dynamic Host Configuration Protocol (DHCP) and Domain
Name System (DNS) options, the default route, Filters, OSPF, 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 enabled (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. Bridging would be more appropriate in a situation where you
are Internet-connected and don’t have a large number of IP addresses.
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
(checked) . It can be disabled, however, if you are using WAN links in Dial on Demand (DOD) mode.
For DOD links, disabling RIP will reduce traffic on the link and it will also disable periodic RIP
broadcasts. RIP routing on a given port will be automatically turned off when DOD 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. In this case, a PPP client connected to the WAN port will be on the same IP network as
the LAN port of the 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 RouteFinder to dynamically
get an IP address for a PPP client coming up on its “Client-only” WAN port. When this option is
enabled, there must be a DHCP server or a DHCP relay agent on the connected LAN in order for the
RouteFinder to acquire an appropriate IP address.
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 Domain Name System (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 details on other parameters, refer
to the online Help provided with your RouteFinder software.
