Loopback - In this state, the router's interface to the network is looped back either in hardware or software.
The interface is unavailable for regular data traffic. However, it may still be desirable to gain information on the
quality of this interface, either through sending ICMP pings to the interface or through something like a bit error
test. For this reason, IP packets may still be addressed to an interface in Loopback state. To facilitate this,
such interfaces are advertised in router- LSAs as single host routes, whose destination is the IP interface
address.
Waiting - The router is trying to determine the identity of the (Backup) Designated Router for the network 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.
Designated Router - This router is itself the Designated Router on the attached network. Adjacencies are
established to all other routers attached to the network. The router must also originate a network-LSA for the
network node. The network- LSA will contain links to all routers (including the Designated Router itself)
attached to the network.
Backup Designated Router - This router is itself the Backup Designated Router on the attached network. It
will be promoted to Designated Router if the present Designated Router fails. The router establishes
adjacencies to all other routers attached to the network. The Backup Designated Router performs slightly
different functions during the Flooding Procedure, as compared to the Designated Router.
Other Designated Router - The interface is connected to a broadcast or NBMA network on which other
routers have been selected to be the Designated Router and Backup Designated Router either. The router
attempts to form adjacencies to both the Designated Router and the Backup Designated Router.
The State is only displayed if the OSPF admin mode is enabled.
。
Designated Router - The identity of the Designated Router for this network, in the view of the advertising router.
The Designated Router is identified here by its router ID. The value 0.0.0.0 means that there is no Designated
Router. This field is only displayed if the OSPF admin mode is enabled.
。
Backup Designated Router - The identity of the Backup Designated Router for this network, in the view of the
advertising router. The Backup Designated Router is identified here by its router ID. Set to 0.0.0.0 if there is no
Backup Designated Router. This field is only displayed if the OSPF admin mode is enabled.
。
Number of Link Events - This is the number of times the specified OSPF interface has changed its state. This field
is only displayed if the OSPF admin mode is enabled.
Command Buttons
。
Configure Authentication - Display a new screen where you can select the authentication method for the virtual
link.
。
Submit - Send the updated configuration to the switch. Configuration changes take effect immediately. These
