The fields for this output are:
INTERFACE ADDRESS |
Interface IP address. |
ATTACHED AREA |
Attached area ID. |
PHYSICAL INTERFACE |
Displays the interface name. |
INTERFACE MASK |
Displays interface subnet mask. |
INTERFACE TYPE |
Can be non-broadcast, multi-access, for example, an ATM connection, VLink (an OSPF virtual link), or VIPA (a Virtual IP Address link). |
STATE |
Can be one of the following: 1 (down) 2
(backup) 4 (looped back) 8 (waiting) 16 (point-to-point) 32 (DR other)
64 (backup DR) 128 (designated router) |
DESIGNATED ROUTER |
IP address of the designated router. |
BACKUP DR |
IP address of the backup designated router. |
DR PRIORITY |
Displays the interface router priority used when selecting the designated router. |
HELLO INTERVAL |
Displays the current hello interval value. |
RXMT INTERVAL |
Displays the current retransmission interval value. |
DEAD INTERVAL |
Displays the current dead interval value. |
TX DELAY |
Displays the current transmission delay value. |
POLL INTERVAL |
Displays the current poll interval value. |
DEMAND CIRCUIT |
Displays the current demand circuit status. |
HELLO SUPPRESS |
Displays whether Hello Suppression is currently on or off. |
SUPPRESS REQ |
Displays whether Hello Suppression was requested. |
MAX PKT SIZE |
Displays the maximum size for an OSPF packet sent out this interface. |
TOS 0 COST |
Displays the interface TOS 0 cost. |
# NEIGHBORS |
Number of neighbors. This is the number of routers whose hellos have been received, plus those that have been configured. |
# ADJACENCIES |
Number of adjacencies. This is the number of neighbors in state Exchange or greater. |
# FULL ADJS |
Number of full adjacencies. This is the number of neighbors whose state is Full (and therefore with which the router has synchronized databases). |
# MCAST FLOODS |
Number of link state updates flooded out the interface (not counting retransmissions). |
# MCAST ACKS |
Number of link state acknowledgments flooded out the interface (not counting retransmissions). |
NETWORK CAPABILITIES |
Displays the capabilities of the interface. |
