This display shows the following information:
TABLE 27 Detailed OSPFv3 interface information
This Field... Displays...
Interface status The status of the interface. Possible status includes the following:
•
Up
•
Down
Type The type of OSPFv3 circuit running on the interface. Possible types include the
following:
•
BROADCAST
•
POINT TO POINT UNKNOWN
IPv6 Address The IPv6 address(es) assigned to the interface.
Instance ID An identifier for an instance of OSPFv3.
Router ID The IPv4 address of the Brocade device. By default, the Brocade router ID is
the IPv4 address configured on the lowest numbered loopback interface. If the
device does not have a loopback interface, the default router ID is the lowest
numbered IPv4 address configured on the device.
Area ID The IPv4 address or numerical value of the area in which the interface belongs.
Cost The overhead required to send a packet through the interface.
State The state of the interface. Possible states include the following:
•
DR – The interface is functioning as the Designated Router for OSPFv3.
•
BDR – The interface is functioning as the Backup Designated Router for
OSPFv3.
•
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 traffic 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.
Transmit delay The amount of time, in seconds, it takes to transmit Link State Updates
packets on the interface.
Priority The priority used when selecting the DR and the BDR. If the priority is 0, the
interface does not participate in the DR and BDR election.
Timer intervals The interval, in seconds, of the hello-interval, dead-interval, and
retransmit-interval timers.
DR The router ID (IPv4 address) of the DR.
BDR The router ID (IPv4 address) of the BDR.
Number of I/F scoped LSAs The number of interface LSAs scoped for a specified area, AS, or link.
DR Election The number of times the DR election occurred.
Delayed LSA Ack The number of the times the interface sent a delayed LSA acknowledgement.
Neighbor Count The number of neighbors to which the interface is connected.
