I need to link a site network to an OpenStack cloud (hosted by Catalyst).

Does anyone have an example of the Cisco side of the configuration? I have configured IPSec protected GRE tunnels in the past - but need to setup this configure to work with OpenStack.

i have a policy defined in OpenStack IKE - SHA1 - 3DES (encr) - group 14 IPSEC - SHA1 - aes-256 - group 14

However the terminology does not really line up to the Cisco configuration.
