Introduction
This document explains the command show ip ospf traffic in OSPFv2 and OSPFv3. The command show ip ospf traffic helps in troubleshooting the OSPF process in more efficient way by displaying the detailed traffic statistics for the OSPF network.
The OSPF traffic statistics are collected and displayed to include the following information:
- OSPF Hello input queue and OSPF process queue status and statistics.
- Global OSPF traffic statistics.
- Per-OSPF-interface traffic statistics.
- Per-OSPF-process traffic statistics.
In case of instability in a OSPF network, the OSPF process queue status and its statistical information can help us to determine how much traffic can be sent to OSPF i.e. the amount of traffic handled by and OSPF process can be determined with this output.
Also the OSPF packet header errors and LSA errors statistics help in having a record of different types of errors found in the OSPF packets.
In case of typical local network environments which has slow links and frequent topology changes occurs, you can monitor the amount of traffic control exchanged between the OSPF process.
Show IP Traffic In OSPFv2
To display the OSPF traffic statistics in a typical OSPFv2 network, use the command show ip ospf traffic
R1#show ip ospf traffic
