  • 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

    Only interface switching is supported.

  • RFC 4552, Authentication/Confidentiality for OSPFv3

  • RFC 4576, Using a Link State Advertisement (LSA) Options Bit to Prevent Looping in BGP/MPLS IP Virtual Private Networks (VPNs)

  • RFC 4577, OSPF as the Provider/Customer Edge Protocol for BGP/MPLS IP Virtual Private Networks (VPNs)

  • RFC 4811, OSPF Out-of-Band Link State Database (LSDB) Resynchronization
