Encryption over Frame-Relay

[pkapoor]

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.

Paras,

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

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.

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.
