OSPFv3 Authentication

OSFPv3 can be configured to authenticate packets using one of the following authentication methods:
  • Authentication trailer

    Authentication trailer allows authentication of OSPFv3 packets using Hashed Message Authentication Code-Secure Hash Algorithm 1 (HMAC-SHA-1) or Hashed Message Authentication Code-Secure Hash Algorithm 256 (HMAC-SHA-256)

  • IP Security (IPsec)

    IPsec secures OSPFv3 communications using ESP only in transport mode, by authenticating each IP packet using SHA-1 of a communication session.

Note: ESP can support encryption, but FastIron currently supports only authentication.
Note: OSPFv3 packets are not authenticated by default. You must configure OSPFv3 authentication as required.

OSPFv3 authentication can be enabled on each interface, virtual link or area.
