IKE phase 1 , Main Mode, how IKE use different hash and encrypt

Hi,

As I was studying IKE phase 1 Main mode (6 msg exchange) , I stumbled across
how IKE Main mode msgs works.

I read that it use different hash and encryption algorithms n MSG 5 & 6,
than it negotiated in MSG 1&2 . However, we only configure one set of
algorithms under " crypto isakmp policy" . So how the single config under
isakmp policy lead to 2 different algorithms in msg 1&2 and MSG 5&6 of the
IKE phase 1 Main mode ?

Regards,

Jeremy
