OSPF
EIGRP Autonomous System Configuration
ISIS
MPLS
Network Type—OSPF interface type. OSPF network type can be non–broadcast multi–address
(NBMA) even on a broadcast media such as Ethernet. This attribute can have one of the following
values:
– broadcast
– nbma
– pointToPoint
pointToMultipoint
–
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. It is ignored if Authentication Type is not "simple".
Hello Interval (sec)—Frequency at which the device will send hello packets on the specified
interface and EIGRP autonomous system number.
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. If more than one router has the same value for this
field, the routers use their router ID as a tie breaker.
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.
Trans. Delay (sec)—The estimated number of seconds it takes to transmit a link-state update packet
over this interface.
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.
