3DES over T1's

[jerry.larson]

My customer has asked for 3DES 168 bit encrytion for all of his data over T1's in a hub and spoke environment. Can some body give me an example.

Hi Jerry

You will probably need to setup site-to-site/L2L tunnels between your sites. You will need to check whether

1) your routers that connect the sites support IPSEC vpn tunnels - there will probably be an IOS that does.

2) Your routers have enough horsepower and memory to add the additional overhead of IPSEC.

Once you have sorted this out here is a link to some configuration examples for site-to-site IPSEC tunnels between routers.
