OSPFv3 Authentication Trailer Configuration

Authentication must be configured on each interface, virtual link, or area as required. The same authentication method must be enabled on peer and neighbor routers to ensure a connection is established and the packets are transmitted successfully.

OSPFv3 authentication trailer is defined in RFC 7166 and RFC 6506. RFC 7166 supersedes RFC 6506 and by default FastIron implements authentication trailer in accordance with RFC 7166. However, some vendor equipment still supports RFC 6506. If your deployment includes vendor equipment that supports RFC 6506, you can configure authentication for the required interfaces or virtual links, as required, using the ospf authentication rfc6506 command.
