Main Mode in IKEv1 uses how many packages for negotiation?
Main Mode in IKEv1 uses six packets for negotiation. This is a well-known characteristic of the Internet Key Exchange (IKE) protocol where Main Mode exchanges a total of six messages to establish a secure connection. In contrast, Aggressive Mode uses only three packets.
If aggressive mode is not selected, the Security Gateway defaults to main mode, performing the IKE negotiation with six packets; aggressive mode performs the IKE negotiation with three packets.
