OSPFv3 Authentication with IPSEC

This feature introduces IPsec support for OSPF version 3 (OSPFv3). IP Security (IPsec) provides a secure way to authenticate senders and encrypt IPv4 traffic between network devices. IPsec offers the benefits of data confidentiality, data integrity, sender authentication, and anti-replay services. OSPFv3 uses the Authentication Header (AH) and the IP Encapsulating Security Payload (ESP) protocols to authenticate routing information.
