Encryption over Frame-Relay

I have two sites connected via a dedicated / private FR circuit. Several servers on one side talk to about 2 servers on the other site. I need to encrypt the data over this circuit and the encryption should be setup on the endpoint routers themselves.

Communication is bi-directional i.e. sessions can be initiated from servers on either side. The routers will also have to NAT the IPs of the servers.

I have never setup encryption over FR (I know Cisco CET w/ GRE but we're looking for options). Can anyone guide me in the right direction?

Thanks.

Re: Encryption over Frame-Relay

Paras,

Please refer the below URL to set up IPSEC Tunnel between two sites:

http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080094634.shtml

In case if you want multicast traffic to flow across the tunnel, you need to do Ipsec Over GRE.

Let me know if it helps.

Re: Encryption over Frame-Relay

Hi Arul,

Thanks for taking time to post those links. I think I should re-phrase my question.

I am aware of IPSec (sorry did not include that in previous post) and CET/GRE encryption mechanisms as being two options for encryption over a link. I wanted to know if there were any alternatives to these two.
