OSPFv3 Authentication Using IPsec

OSPFv3 uses IPsec to provide authentication for OSPFv3 packets. IPsec authentication ensures security in
the transmission of OSPFv3 packets between IPsec-enabled routers.
IPsec is a set of protocols developed by the internet engineering task force (IETF) to support secure
exchange of packets at the IP layer. IPsec supports two encryption modes: transport and tunnel.
• Transport mode — encrypts only the data portion (payload) of each packet, but leaves the header
untouched.
• Tunnel mode — is more secure and encrypts both the header and payload. On the receiving side, an
IPsec-compliant device decrypts each packet.
NOTE: Dell Networking OS supports only Transport Encryption mode in OSPFv3 authentication with
IPsec.
With IPsec-based authentication, Crypto images are used to include the IPsec secure socket application
programming interface (API) required for use with OSPFv3.
To ensure integrity, data origin authentication, detection and rejection of replays, and confidentiality of
the packet, RFC 4302 and RFC 4303 propose using two security protocols — authentication header (AH)
and encapsulating security payload (ESP). For OSPFv3, these two IPsec protocols provide interoperable,
high-quality cryptographically-based security.
• HA — IPsec authentication header is used in packet authentication to verify that data is not altered
during transmission and ensures that users are communicating with the intended individual or
organization. Insert the authentication header after the IP header with a value of 51. AH provides
