OSPF Network Type—OSPF network type. ATM is a point-to-point service; by default it is
considered to be non–broadcast by the OSPF routing process. An ATM interface can, however, be
configured as a broadcast interface. The OSPF network type can also be dependent on the ATM
network configuration, whether the network is partially meshed or fully meshed.
Area ID—The predefined ID uniquely identifying the area to which the interface connects. It can be
specified as either a decimal value or as an IP address. Value is 0.0.0.0 if interface is a layer 2 (no
IP address assigned) interface. This attribute is read-only.
Authentication Key—Password to be used by neighboring OSPF routers on a network segment that
is using OSPF simple password authentication. This password is ignored if OSPF Authentication
Type is not "simple". This attribute is read-only.
Hello Interval—Length of time between the hello packets sent on an OSPF interface. Must be
consistent among all routers on an attached network. This attribute is read-only.
Trans. Priority—The priority of this interface. Used in multiaccess networks, this field is used in the
designated router election algorithm. The value 0 signifies that the router is not eligible to become
the designated router on this particular network. In the event of a tie in this value, routers will use
their Router ID as a tie breaker. This attribute is read-only.
Trans. Dead (sec)—Number of seconds that a device's hello packets must not have been seen before
its neighbors declare the OSPF router down. Must be consistent among all routers on an attached
network. This attribute is read-only.
Trans. Delay (sec)—Estimated number of seconds it takes to send a link-state update packet this
interface. This attribute is read-only.
Retrans. Interval (sec)—The number of seconds between link-state advertisement retransmissions,
for adjacencies belonging to this interface. This value is also used when retransmitting database
description and link-state request packets. This attribute is read-only.
