TABLE 59 show ip ospf interface output descriptions (continued)
This eld Displays
State The state of the interface. Possible states include the following:
• DR - The interface is functioning as the Designated Router for
OSPFv2.
• BDR - The interface is functioning as the Backup Designated
Router for OSPFv2.
• Loopback - The interface is functioning as a loopback interface.
• P2P - The interface is functioning as a point-to-point interface.
• Passive - The interface is up but it does not take part in forming
an adjacency.
• Waiting - The interface is trying to determine the identity of the
BDR for the network.
• None - The interface does not take part in the OSPF interface
state machine.
• Down - The interface is unusable. No protocol trac can be sent
or received on such a interface.
• DR other - The interface is a broadcast or NBMA network on
which another router is selected to be the DR.
• Active - The interface sends or receives all the OSPFv2 control
packets and forms the adjacency.
default Shows whether or not the default passive state is set.
Pri The interface priority.
Cost The congured output cost for the interface.
