Configuring a default route

A default route is a static route that specifies a destination for addresses that are not
on the local network and to which a known route does not exist. The default route is
generally the IP address of an external router that has more route information about
how specific destinations can be reached. When the default route is configured, the
Stinger MRT unit routes all IP packets with unknown destinations to the specified
external router. If no default route is defined, the unit drops IP packets for which it
has no route.
Figure 6-3 shows the Stinger MRT Ethernet interfaces on a subnet, connected to the
same Ethernet segment as a local backbone router. In this network, the Stinger MRT
can use the local router as its default route.
Figure 6-3. Local backbone router to be used as default route
Assuming a local router as the unit's default route, or gateway, enables the Stinger
MRT unit to pass all IP packets with an unrecognized address to that router, so its
own routing tables can remain small. The external router maintains larger routing
tables, and assumes the responsibility and overhead of routing most packets.
For example, the following commands define a default route to the LAN router in
Figure 6-3:
admin> new ip-route default
IP-ROUTE/default read
admin> set gateway-address = 1.1.1.3
admin> set active-route = yes
admin> write
IP-ROUTE/default written
The system can support multiple default routes. The profile name does not have to be
default. The only requirements are that the destination address must be zero, and
Gateway-Address must specify a valid, accessible router.
For information about other settings in the IP-Route profile, see the Stinger Reference.

Additional administrative connections and configuration

Administration of the Stinger MRT can be managed from a remote workstation over
several different types of connections.
An Ethernet LAN
An analog modem (internal or external)
