The original specification allows weak security and suggests algorithms that are thinly implemented. This document updates RFC , the original specification, and is intended for all IKEv1 implementations deployed today.

This document updates RFC by changing the algorithm requirements defined there. Section 4 of that specification says that "IKE implementations Note that some of the requirements are the same as those in RFC , whereas others are changed.
