  • RFC 2154, OSPF with Digital Signatures

  • RFC 2328, OSPF Version 2

  • RFC 2370, The OSPF Opaque LSA Option

    Support is provided by the update-threshold configuration statement at the [edit protocols rsvp interface interface-name ] hierarchy level.

  • RFC 3101, The OSPF Not-So-Stubby Area (NSSA) Option

  • RFC 3623, Graceful OSPF Restart
