OSPFv3 authentication

http://packetlife.net/blog/2008/sep/3/ospfv3-authentication/


Most IPv4 routing protocols support some form of neighbor authentication, provided by either a plaintext password or MD5 HMAC. However, OSPFv3 (OSPF for IPv6) doesn't include any authentication capabilities of its own; instead, it relies entirely on IPsec to secure communications between neighbors. This is beneficial in simplifying the OSPFv3 protocol and standardizing its authentication mechanism.
