1158 CHAPTER 76: OSPF CONFIGURATION COMMANDS

View	OSPF area view
Parameters	no-summary: Used only on a stub ABR. With it configured, the ABR advertises
	only a default route in a Summary LSA into the stub area (Such a stub area is
	known as a totally stub area).
Description	Use the stub command to configure an area as a stub area.
	Use the undo stub command to remove the configuration.
	No area is a stub area by default.
	To cancel the no-summaryconfiguration on an ABR, use the stub command
	again to overwirte the previous configuration.
	To configure an area as a stub area, all routers attached to it must be configured
	with this command.

stub-router

Syntax	stub-router
	undo stub-router
View	OSPF view
Parameters	None
Description	Use the stub-routercommand to configure the router as a stub router.
	Use the undo stub-routercommand 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.
