Open Shortest Path First (OSPF)

XXX - add a brief OSPF description here

History

XXX - add a brief description of OSPF history

Protocol dependencies

• IP: Typically, OSPF uses IP as its transport protocol. The well known IP protocol type for OSPF traffic is 0x59.

Example traffic

XXX - Add example traffic here (as plain text or Wireshark screenshot).

Wireshark

The OSPF dissector is (fully functional, partially functional, not existing, ... whatever the current state is). Also add info of additional Wireshark features where appropriate, like special statistics of this protocol.

Preference Settings

(XXX add links to preference settings affecting how OSPF is dissected).

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.

Display Filter

A complete list of OSPF display filter fields can be found in the display filter reference

• Show only the OSPF traffic:

   ospf 

Capture Filter

You cannot directly filter OSPF protocols while capturing. However, if you know the IP protocol type used (see above), you can filter on that one.

• Capture OSPF traffic:

   ip proto ospf 

  or, if that gets a parse error:

   ip proto 0x59

• RFC 2740 OSPF for IPv6 - describes OSPF version 3
