Abstract
A method for providing control plane encryption in layer 3 networks is disclosed. The method for providing control plane encryption in layer 3 networks includes for a network having a subset of network elements forming a secured domain; the steps of at a network element which is in the secured domain, encrypting all unencrypted Layer 3 packets as they egress an encryption enable egress interface; unencrypting all encrypted Layer 3 packets as they egress an egress interface is not enabled for encryption; and leaving encrypted all encrypted Layer 3 packets as they egress an encryption enable egress interface. A system and machine readable storage media are also disclosed.
