7.6.4 Page 4: IKE Phase 2

Perfect Forward Secrecy (PFS): Enabling this feature will

require IKE to generate a new set of keys in Phase 2 rather than

using the same key generated in Phase 1.

Additionally, the new keys generated in Phase 2 (with this option

enabled) are exchanged in an encrypted session. Enabling this

feature affords the policy greater security.

Key Lifetime: The lifetime of the generated keys of Phase 2 of

the IPsec negotiation from IKE. After the time has expired, IKE

will renegotiate a new set of Phase 2 keys.

Phase 2 has the same selection of Encryption, Hash, and DH

Groups as Phase 1, but you are restricted to only one DH

Group. Phase 2 and Phase 1 selections do not have to match.
