Multiple proposals can be sent in one offering. The next exchange passes Diffie-Hellman public keys and other data. Aggressive Mode Aggressive Mode squeezes the IKE SA negotiation into three packets, with all data required for the SA passed by the initiator. The responder sends the proposal, key material and ID, and authenticates the session in the next packet. The initiator replies by authenticating the session.
Negotiation is quicker, and the initiator and responder ID pass in the clear.

Please check back for information on revised event dates. Thank you for understanding.
