ESP and AH

Hi,

We have two different security mechanisms - ESP and AH. ESP provides Authentication,Intigrity and Encryption while AH provides Authentication and Intogrity only. Why do we need to use both mechanisms combinly in a tunnel? Why dont we use ESP alone or AH alone? Please correct me if I am wrong.

Re: ESP and AH

We can establish tunnel with ESP or AH alone,it is not required to use both, the only reason you would like to use both for tunnel is to have additional security .
