OSPF RFC compliance

The OSFP features covered in this guide comply with the following:
  • RFC 2328 OSPF version 2

  • RFC 3101 OSPF NSSA option

  • RFC 1583 (Enabled in the default OSPF configuration. See the following Note.)

  • RFC 4750 MIB variables.

NOTE:

If all of the routers in your OSPF domain support RFC 2178, RFC 2328, or later, you should disable RFC 1583 compatibility on all routers in the domain. See Changing the RFC 1583 OSPF compliance setting.
