OSPF WG has come out with a mechanism that can be used to secure OSPFv3 without IPsec - http://tools.ietf.org/html/draft-ietf-ospf-auth-trailer-ospfv3-11 It should get published as an RFC any time now. BTW, there isnt any standard for using IPsec with OSPFv2, so youre probably using a proprietary solution. I think a better solution is to move to OSPFv3-AT, as its very similar to OSPFv2 authentication. Glen
