OSPF Commands

To create or modify a routing configuration file, you must use the correct routing commands. This list includes the supported routing commands for OSPF. The sections must appear in the configuration file in the same order they appear in this list. You can also use the sample text found in the Sample OSPF Routing Configuration File.

For more information about Quagga commands, see Quagga Routing Suite Documentation.

Section	Command	Description
Configure Interface
	interface eth[N]	Begin section to set properties for interface
	ip ospf authentication-key [PASSWORD]	Set OSPF authentication password
	ip ospf message-digest-key [KEY-ID] md5 [KEY]	Set MD5 authentication key ID and key
	ip ospf cost [1-65535]	Set link cost for the interface (see OSP Interface Cost table below)
	ip ospf hello-interval [1-65535]	Set interval to send hello packets; default is 10 seconds
	ip ospf dead-interval [1-65535]	Set interval after last hello from a neighbor before declaring it down; default is 40 seconds
	ip ospf retransmit-interval [1-65535]	Set interval between link-state advertisements (LSA) retransmissions; default is 5 seconds
	ip ospf transmit-delay [1-3600]	Set time required to send LSA update; default is 1 second
	ip ospf priority [0-255]	Set route priority; high value increases eligibility to become the designated router (DR)
Configure OSPF Routing Daemon
	router ospf	Enable OSPF daemon
	ospf router-id [A.B.C.D]	set router ID for OSPF manually; router determines its own ID if not set
	ospf rfc1583compatibility	Enable RFC 1583 compatibility (can lead to route loops)
	ospf abr-type [cisco\|ibm\|shortcut\|standard]	More information about this command can be found in draft-ietf-abr-o5.txt
	passive-interface eth[N]	Disable OSPF announcement on interface eth[N]
	auto-cost reference-bandwidth[0-429495]	Set global cost (see OSPF cost table below); do not use with ip ospf [COST] command
	timers spf [0-4294967295][0-4294967295]	Set OSPF schedule delay and hold time
Enable OSPF on a Network
The area* variable can be typed in two formats: [W.X.Y.Z]; or as an integer [Z].
	network [A.B.C.D/M] area [Z]	Announce OSPF on network A.B.C.D/M for area 0.0.0.Z
Configure Properties for Backbone area or Other Areas
The area variable can be typed in two formats: [W.X.Y.Z]; or as an integer [Z].
	area [Z] range [A.B.C.D/M]	Create area 0.0.0.Z and set a classful network for the area (range and interface network and mask setting should match)
	area [Z] virtual-link [W.X.Y.Z]	Set virtual link neighbor for area 0.0.0.Z
	area [Z] stub	Set area 0.0.0.Z as a stub
	area [Z] stub no-summary
	area [Z] authentication	Enable simple password authentication for area 0.0.0.Z
	area [Z] authentication message-digest	Enable MD5 authentication for area 0.0.0.Z
Redistribute OSPF Routes
	default-information originate	Share route of last resort (default route) with OSPF
	default-information originate metric [0-16777214]	Share route of last resort (default route) with OSPF, and add a metric used to generate the default route
	default-information originate always	Always share the route of last resort (default route)
	default-information originate always metric [0-16777214]	Always share the route of last resort (default route), and add a metric used to generate the default route
	redistribute static	Redistribute firewall static routes to OSPF
	redistribute connected	Redistribute routes from all interfaces to OSPF
	redistribute connected metrics	Redistribute routes from all interfaces to OSPF, and a metric used for the action
Configure Route Redistribution with Access Lists and Route Maps
	access-list [LISTNAME] permit [A.B.C.D/M]	Create an access list to allow distribution of A.B.C.D/M
	access-lists [LISTNAME] deny any	Restrict distribution of any route map not specified above
	route-map [MAPNAME] permit [N]	Create a route map with name [MAPNAME] and allow with a priority of [N]
	match ip address [LISTNAME]
