Anthony,
A network with a single entrance and exit is a stub network, but
that's not the definition of a stub network. A stub network is a
network that only provides connectivity for local hosts. Even if the
network has more than one entry and exit it can still be a stub network
by not allowing transit traffic.
HTH,

A stub network is one that only features a single point of entrance and
exit
into this area of your overall network. For a picture of one - visit:

You usually want to treat these stub networks in a special manner - for
example - a default route can be used to get out of the stub network -
there
is no need for full routing tables in the stub network.
OSPF and EIGRP have sophisticated ways of dealing with these stub
networks
built in! For example - in OSPF you can use the STUB AREA features to
automatically handle the needs of stub networks.
