| Format | show ipv6 ospf statistics |
| Mode |

The command displays the following information with the most recent statistics displayed at the end of the table.
| Term | Definition |
|---|---|
| Delta T | The time since the routing table was computed. The time is in the format hours, minutes, and seconds hh:mm:ss). |
| Intra | The time taken to compute intra-area routes, in milliseconds. |
| Summ | The time taken to compute inter-area routes, in milliseconds. |
| Ext | The time taken to compute external routes, in milliseconds. |
| SPF Total | The total time taken to compute routes, in milliseconds. The total may exceed the sum of Intra, Summ, and Ext times. |
| RIB Update | The time from the completion of the routing table calculation until all changes have been made in the common routing table [the Routing Information Base (RIB)], in milliseconds |
| Reason | The event or events that triggered the SPF. The reason codes are as follows:
