AT8901M CLI Reference Manual

Attempt - no recent information has been received from the neighbor
but a more concerted effort should be made to contact the neighbor.

Init - an Hello packet has recently been seen from the neighbor, but
bidirectional communication has not yet been established.

2 way - communication between the two routers is bidirectional.

Exchange start - the first step in creating an adjacency between the two
neighboring routers, the goal is to decide which router is the master
and to decide upon the initial DD sequence number.

Exchange - the router is describing its entire link state database by
sending Database Description packets to the neighbor.

Loading - Link State Request packets are sent to the neighbor asking
for the more recent LSAs that have been discovered (but not yet
received) in the Exchange state.

Full - the neighboring routers are fully adjacent and they will now
appear in router-LSAs and network-LSAs.

Dead Time

The amount of time, in seconds, to wait before the router assumes the
neighbor is unreachable.

If you specify an IP address for the neighbor router, the following fields display:
Interface

Valid slot and port number separated by forward slashes.

Neighbor IP Address The IP address of the neighbor router.
Interface Index The interface ID of the neighbor router.
Area ID

The area ID of the OSPF area associated with the interface.

Options

An integer value that indicates the optional OSPF capabilities sup-
ported by the neighbor. The neighbor's optional OSPF capabilities are
also listed in its Hello packets. This enables received Hello Packets to
be rejected (i.e., neighbor relationships will not even start to form) if
there is a mismatch in certain crucial OSPF capabilities.

Router Priority The OSPF priority for the specified interface. The priority of an

interface is a priority integer from 0 to 255. A value of '0' indicates that
the router is not eligible to become the designated router on this net-
work.

Dead Timer Due The amount of time, in seconds, to wait before the router assumes

the neighbor is unreachable.

State

The state of the neighboring routers.

Events

The number of times this neighbor relationship has changed state, or
an error has occurred.

Retransmission Queue Length An integer representing the current length of the

retransmission queue of the specified neighbor router Id of the speci-
fied interface.
