Displaying OSPFv3 results

The show ipv6 ospf command and its variations can be used to display information about OSPFv3 configurations.

Before you begin

About this task

Use one or more of the following commands to verify OSPFv3 information. Using the show ipv6 ospf command is optional, and the variations of the command can be entered in any order.

Procedure

  1. Enter the show ipv6 ospf command to display general OSPFv3 information. 
    device# show ipv6 ospf 
OSPFv3 Process number 0 with Router ID 0xc0a80001(192.168.0.1)
Running 0 days 0 hours 49 minutes 2 seconds
Number of AS scoped LSAs is 1
Sum of AS scoped LSAs Checksum is 0000d72f
External LSA Limit is 250000
Database Overflow Interval is 10
Database Overflow State is NOT OVERFLOWED
Route calculation executed 10 times
Pending outgoing LSA count 0
Authentication key rollover interval 300 seconds
Number of areas in this router is 3
Router is operating as ABR
Router is operating as ASBR, Redistribute: STATIC
High Priority Message Queue Full count: 0
BFD is disabled, BFD HoldoverInterval: 0
Graceful restart helper is enabled, strict lsa checking is disabled
Nonstop Routing is enabled
Administrative Distance
- External Routes: 110
- Intra Area Routes: 110
- Inter Area Routes: 110
Maximum Paths: 8
    The example output offers general OSPFv3 information and indicates that the device is not operating as an ASBR. If the device is not operating as an ASBR, there is no information about redistribution in the output.
  2. The following example of the show ipv6 ospf summary command shows summary output for the one IPv6 OSPF session that is configured. 
    device# show ipv6 ospf summary 
Total number of IPv6 OSPF instances: 1

Seq Instance                        Intfs   Nbrs    Nbrs-Full LSAs    Routes

  3. The following example of the show ipv6 ospf summary all-vrfs total command shows the cumulative summary output for OSPFv3 sessions. 
    device# show ipv6 ospf summary all-vrfs total
-----------------------------------------
         IPv6 OSPF Summary Total

  4. The following example of the show ipv6 ospf neighbor command shows OSPFv3 neighbor information for the device.
    Note

    Note

    QCount is the LSA retransmission list count. The number displays the number of LSAs that are waiting for acknowledgements.
