Use display ospfv3 event-log to display OSPFv3 log information.

Syntax

display ospfv3 [ process-id ] event-log { lsa-flush | peer | spf }

Parameters

process-id: Specifies an OSPFv3 process by its ID in the range of 1 to 65535. If you do not specify this argument, the command displays OSPFv3 log information for all processes.

lsa-flush: Specifies LSA aging log information.

peer: Specifies neighbor log information.

spf: Specifies route calculation log information.

Usage guidelines

Route calculation logs show the number of routes newly installed in the IPv6 routing table.

Neighbor logs include information about the following events:

The OSPFv3 neighbor state goes down.
The OSPFv3 neighbor state goes backward because the local end receives BadLSReq, SeqNumberMismatch, and 1-Way events.

Examples

# Display OSPFv3 LSA aging log information for OSPFv3 process 1.
