Description
Use the stub-router command to configure the router as a stub router.
Use the undo stub-router command to restore the default.
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.
Examples
