Phase 2 Configuration
Phase 2 establishes the IPsec Security Associations (SA)
parameters in order to establish an IPsec tunnel. Phase 2 has
one mode called Quick mode, it starts after IKE has started
a secure tunnel in phase 1. Quick mode is also used to re-
negotiate a new IPsec SA when the current IPsec SA lifetime
expires.
The phase 2 options are:
ESP proposal
Encapsulating Security Payload (ESP) is used to encrypt the
data transmitted in IP datagrams. The proposal establishes the
Encryption algorithm and Authentication protocol to use.
