OSPFv3 Authentication Using IPsec
OSPFv3 authentication using IP security (IPsec) is supported the MXL switch.
Starting in Dell Networking OS version 8.4.2.0, 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: The Dell Networking OS supports only Transport Encryption mode in OSPFv3 authentication
with IPsec.
