By default, no router is configured as a stub router.
The router LSAs from the stub router may contain different link type values. A
value of 3 means a link to the stub network, so the cost of the link remains
unchanged. A value of 1, 2 or 4 means a point-to-point link, a link to a transit
network or a virtual link; in such cases, a maximum cost value of 65535 is used.
Thus, other neighbors find the links to the stub router have such big costs, they
will not send packets to the stub router for forwarding as long as there is a route
with a smaller cost.
