In order to do this, when you define the trustpoint under the crypto map add the chain keyword as shown here: If this is not done, then the the tunnel only gets negotiated as long as the ASA is the responder. You can use a ping in order to verify basic connectivity. Establish a policy for the supported ISAKMP encryption, authentication Diffie-Hellman, lifetime, and key parameters.
