	area 0.0.0.0 is created.

enable ospf

enable ospf exportstatic type [1 2]

config ospf [vlan <name> area <areaid> virtual-link <routerid> <areaid>] authentication [simple-password <password> md5 <md5_key_id> <md5_key> none]

config ospf vlan <name> area <areaid>

config ospf [vlan <name> area <areaid> all] cost <number>

config ospf [vlan <name> area <areaid> all] priority <number>

config ospf add [vlan <name> all]

Enables OSPF process for the router.

Exports statically configured routes to other OSPF routers. The default setting is disabled.

Specifies the authentication password (up to 8 characters) or MD5 key for one or all interfaces in an area. The <md5_key> is a numeric value with the range 0 - 65536. When the OSPF area is specified, authentication information is applied to all OSPF interfaces within the area.

Associates a VLAN (router interface) with an OSPF area. All router interfaces must have an associated OSPF area. The default <areaid> is 0 (backbone area).

Configures the cost metric of one or all interface(s). The default cost is 1.

Configures the priority used in the designated router election algorithm for one or all IP interface(s) of for all the interfaces within the area. The range is 0 through 255, and the default setting is 1.

Enables OSPF on one or all VLANs (router interfaces). The default setting is disabled.

config ospf delete [vlan <name> all]	Disables OSPF on one or all VLANs (router
	interfaces).
config ospf add virtual-link <routerid> <areaid>	Adds a virtual link connected to another ABR.
	Specify the following:
	■ routerid — Far end router interface
	number.
	■ areaid — Transit area used for connecting
	the two end-points. The transit area cannot
