Cisco 2921 ISR2 IOS 15.0 router GRE over IPsec configuration problem

Hi Folks,

I need a little help with configuration of a 2921 ISR2 router. I am trying to configure GRE over IPsec as a backup link (primary link is on a metro-ethernet) with OSPF. However I don't see an option to enable crypto isakmp policy #. I don't see an option to enable it, below is the show version and help options availble for crypto. Am I missing a step? or do I have the wrong IOS version?

Re: Cisco 2921 ISR2 IOS 15.0 router GRE over IPsec configuration

It's because your IOS feature is "IP Base".  I believe GRE support require IP Services.
