Table 2-27 explains the fields for each ospf interface entry.
 
Table 2-27: show ipv6 ospf interface output details
Field
Description
Interface Type and whether it is up or down.
Status of the interface type.
Line protocol
Status of the line protocol.
Interface ID
Interface for which information is displayed.
Instance ID
For running multiple instances of OSPFv3 on the router
Area
Area ID in A.B.C.D form
IPv6 Link-Local Address
link-local address is an IPv6 unicast address – cannot communicate to link-local addresses that are outside the directly connected network. In IPv6 (X:X::X:X/M) form.
Router ID
As stated – In A.B.C.D form.
Network Type
One of the following:
Ethernet is Broadcast
Serial p2p non-broadcast
NBMA – Non-Broadcast MultiAccess (NBMA) media
cost
The cost of sending packets over this interface – range is 1 to 65535.
Transmit Delay
The delay, in seconds, between link-state transmits. This value must be the same for all nodes on the network. The range is 1 to 65535. The default is 1.
Priority
OSPFv3 router priority for the interface. The range is 0 to 255. A router with priority 0 can never become the designated router, the default is 1.
Designated Router (ID)
The ID number of the Designated Router (DR).
Interface Address
The IPV6 address of this device.
Backup Designated Router
The ID number or the Backup Designated Router (BDR).
Interface Address
The IPv6 address of the Backup Designated Router.
Timer interval configured
The timer values of the following instances: Hello, Dead, Wait, Retransmit.
Hello due in
The countdown for receiving the next Hello packet.
Neighbor Count is
Number of neighbor count.
Adjacent neighbor count is
Number of adjacent neighbor count.
