gated.conf(4) gated.conf(4)

utility sends non-standard OSPF packets which generate a text response from OSPF. By default

these requests are not authenticated, if an authentication key is conﬁgured, the incoming requests

must match the speciﬁed authentication key. No OSPF state may be changed by these packets, but

the act of querying OSPF can utilize system resources.

backbone

area area

Each OSPF router must be conﬁgured into at least one OSPF area. If more than one area is

conﬁgured, at least one must the be backbone. The backbone may only be conﬁgured using the

backbone keyword, it may not be speciﬁed as area 0. The backbone interface may be a virtu-

allink.

authtype 0 | 1 | none | simple

OSPF speciﬁes an authentication scheme per area. Each interface in the area must use this

same authentication scheme although it may use a different authenticationkey. The

currently valid values are none (0) for no authentication, or simple (1) for simple password

authentication.

stub [ cost cost]

A stub area is one in which there are no ASE routes. If a cost is speciﬁed, this is used to

inject a default route into the area with the speciﬁed cost.

networks

The networks list describes the scope of an area. Intra-area LSAs that fall within the

speciﬁed ranges are not advertised into other areas as inter-area routes. Instead, the speciﬁed

ranges are advertised as summary network LSAs. If restrict is speciﬁed, the summary net-

work LSAs are not advertised. Intra-area LSAs that do not fall into any range are also adver-

tised as summary network LSAs. This option is very useful on well designed networks in

reducing the amount of routing information propagated between areas. The entries in this list

are either networks, or a subnetwork/mask pair. See the section on Route Filtering for more

detail about specifying ranges.

stubhosts

This lists speciﬁes directly attached hosts that should be advertised as reachable from this

router and the costs they should be advertised with. Point-to-point interfaces on which it is not

desirable to run OSPF should be speciﬁed here.

It is also useful to assign a additional address to the loopback interface (one not on the 127

network) and advertise it as a stub hosts. If this address is the same one used as the router-id,

it enables routing to OSPF routers by router-id, instead of by interface address. This is more

reliable than routing to one of the routers interface addresses which may not always be reach-

able.

interface interface_list [cost cost ]

This form of the interface clause is used to conﬁgure a broadcast (which requires IP multi-

cast support) or a point-to-point interface. See the section on interface list speciﬁcation

for the description of the interface_list.

Each interface has a cost. The costs of all interfaces a packet must cross to reach a destina-

tion are summed to get the cost to that destination. The default cost is one, but another non-

zero value may be speciﬁed.

Interface parameters common to all types of interfaces are:

retransmitinterval time

The number of seconds between link state advertisement retransmissions for adja-

cencies belonging to this interface.

transitdelay time

The estimated number of seconds required to transmit a link state update over this

interface. Transitdelay takes into account transmission and propagation delays and

must be greater than 0.

priority priority

A number between 0 and 255 specifying the priority for becoming the designated

router on this interface. When two routers attached to a network both attempt to

become designated router, the one with the highest priority wins. A router whose

router priority is set to 0 is ineligible to become designated router.
