That's right.

I am clear about the part that OSPF is not doing any authentication and
IPsec is going to provide the security required. Since OSPF is going to send
both unicast and multicast traffic and it is going to be a point to
multipoint security, the implementation is little more involved. I was
wondering if there is any standard way of taking care of the issues.

Is there any vendor out there who has implemented this or planning to
implement this in near future ??
