show ipv6 ospf interface

Use this command to display OSPFv3 interface related information, including network type, priority, cost, hello interval, and dead interval.

Syntax

show ipv6 ospf [process-id]interface [ifName]

Parameters

process-id (Optional) Specifies a configured OSPFv3 process by its process ID. If process-id is included, information for the specified routing process only is displayed.
ifName (Optional) Displays OSPFv3 information for an interface, such as a specific VLAN. The interface must be configured for IP routing as described in the S-, K-, and 7100 Series Configuration Guide.

Defaults

If ifName is not specified, OSPFv3 statistics are displayed for all interfaces (including VLANs).

Mode

All command modes.

Example

This example shows how to display all OSPFv3 related information for VLAN 23:

System(rw)->show ipv6 ospf interface vlan.0.23
vlan.0.23 is UP
  Process Id 60 Router Id 41.0.0.0, Network Type BROADCAST, Cost: 10
  Area Id is 0.0.0.0, Transmit Delay is 1 sec, State DESIGNATED-ROUTER, Priority 1
  Designated Router IfIndex 23
  No backup designated router on this network
  Timer intervals configured: Hello 10, Dead 40, Wait 40, Retransmit 5
  Neighbor Count is 0, Adjacent neighbor count is 0

show ipv6 ospf interface Output Details

Output... What it displays...
Vlan.x.y is Interface (VLAN) administrative status as up or down.
Process Id OSPFv3 Process ID.
Router Id Router ID for this router.
Network Type OSPFv3 network type: non-broadcast, broadcast, point-to-point, or point-to-multipoint
Cost OSPFv3 interface cost, which is either default, or assigned with the ipv6 ospf cost command. For details, refer to ipv6 ospf cost.
Area Id The Area ID that this interface is a member of in dotted-quad notation.
Transmit Delay The number (in seconds) added to the LSA (Link State Advertisement) age field.
State The interface state (versus the state between neighbors). Valid values include BACKUP-DESIGNATED-ROUTER and DESIGNATED-ROUTER.
Priority The interface priority value, which is either default, or assigned with the ipv6 ospf priority command. For details, refer to ipv6 ospf priority.
Designated Router IfIndex Interface index of the designated router on this subnet, if one exists.
Backup Designated Router IfIndex Interface index of the backup designated router on this interface, if one exists.
Timer intervals configured OSPFv3 timer intervals. These are either default, or configured with the ipv6 ospf retransmit-interval (ipv6 ospf retransmit-interval), the ipv6 ospf hello-interval (ipv6 ospf hello-interval), and the ipv6 ospf dead interval (ipv6 ospf dead-interval) commands.

The wait timer represents the amount of time a router waits before initiating a designated router/backup designated router election. The wait timer value is the same as the dead interval timer value.

The retransmit timer represents the amount of time between successive transmissions of LSAs (Link State Advertisements) until acknowledgement is received.

Neighbor Count Number of neighbors on this interface.
Adjacent neighbor count Number of adjacent (FULL state) neighbors over this interface.
