An SCS in a small sales office might have a default route that points to the corporate headquarters. The SCS
doesn't need to know about all of the routes on the headquarters network. It only knows to send all otherwise
unspecified traffic to the central location, where it will be routed to the final destination.
6.7.2.2 Adding Routes to the Table
Entries may be added to the routing table in three ways: locally, statically, or dynamically.
Locally
A Host Route is a route to a single host. Generally, a host route is entered for
each Remote Node that logs into the SCS.
A network route is a route to another network. A network route is used if a host
route to the destination doesn't exist.
A default route is used if a more specific host or network route isn't available.
It is used to cut down on the size of routing tables and dynamic routing protocol
updates. If, for example, the SCS is the only path for network packets to reach
a much larger group of networks, the SCS can be configured to advertise itself
as the default route.
When a route is added locally, it is automatically determined from the SCS IP
address and network mask. The SCS always keeps a local route to the Ethernet
that is attached to; this route is never deleted.
