None
- This is the initial interface state. If you select this option from the pulldown menu on
the second screen you will be returned to the first screen.
Simple
- If you select 'Simple' you will be prompted to enter an authentication key. This key
will be included, in the clear, in the OSPF header of all packets sent on the network. All
routers on the network must be configured with the same key.
Encrypt
- If you select 'Encrypt' you will be prompted to enter both an authentication key and
an authentication ID. Encryption uses the MD5 Message-Digest algorithm. All routers on the
network must be configured with the same key and ID.
Authentication Key
- Enter the OSPF Authentication Key for the specified interface. If you do not
choose to use authentication you will not be prompted to enter a key. If you choose 'simple'
authentication you cannot use a key of more than 8 octets. If you choose 'encrypt' the key may be up
to 16 octets long. The key value will only be displayed if you are logged on with Read/Write
privileges, otherwise it will be displayed as asterisks.
Authentication ID
- Enter the ID to be used for authentication. You will only be prompted to enter an
ID when you select 'Encrypt' as the authentication type. The ID is a number between 0 ad 255,
inclusive.
Non-Configurable Data
State
- The current state of the selected Virtual Link. One of:
Down
- This is the initial interface state. In this state, the lower-level protocols have indicated that the
interface is unusable. In this state, interface parameters will be set to their initial values. All interface
timers will be disabled, and there will be no adjacencies associated with the interface.
Waiting
- The router is trying to determine the identity of the (Backup) Designated Router by
monitoring received Hello Packets. The router is not allowed to elect a Backup Designated Router or
a Designated Router until it transitions out of Waiting state. This prevents unnecessary changes of
(Backup) Designated Router.
Point-to-Point
- The interface is operational, and is connected to the virtual link. On entering this
state the router attempts to form an adjacency with the neighboring router. Hello Packets are sent to
the neighbor every HelloInterval seconds.
Neighbor State
- The state of the Virtual Neighbor Relationship.
