HAPTER 12: CONFIGURING IP ROUTING
IP Address IP address of the neighboring router.
Priority Priority of this neighbor in the designated router election
algorithm. A value of zero signifies that the neighbor is not
eligible to become the designated router on this particular
network.
Adjacency State State of the Neighbor from the perspective of the Cuda
12000. This is based upon the messages that the Cuda
12000 has received from the neighboring router. The options
are:
Down. Cuda 12000 has not heard from the neighbor within
the period specified by the dead-interval OSPF interface
configuration parameter.
Attempt. This is a valid state only when OSPF is configured on
a non-broadcast network. The attempt state indicates that no
recent information has been received from the neighbor, but
that a more concerted effort should be made to contact the
neighbor. This is done by sending the neighbor Hello packets
at intervals of Hello Interval. You can do this by configuring
the Hello Interval on this interface.
Init. The Cuda 12000 receives a OSPF Hello message from the
neighboring router. However, bidirectional communication
has not yet been established with the neighbor; that is the
Cuda 12000 did not appear in the neighbor's Hello packet).
All neighbors in this state (or higher) are listed in the Hello
packets sent by the Cuda 12000 on the associated interface.
Two Way. Communication between the Cuda 12000 and the
neighboring router is now bidirectional. This has been
assured by the fact that the Cuda 12000 is listed as a router
in the last Hello packet received from the neighboring router.
This is the most advanced state short of beginning adjacency
establishment. The (Backup) Designated Router is selected
from the set of neighbors in state 2-Way or greater.
Exchange Start. This is the first step in creating an adjacency
between the two neighboring routers. The goal of this step is
to decide which router is the master, and to decide upon the
initial DD sequence number. Neighbor conversations in this
state or greater are called adjacencies.
Exchange. In this state the Cuda 12000 is distributing its
entire link state database by sending Database Description
packets to the neighbor.
