Implementing Internet Key Exchange Security
Protocol on Cisco IOS XR Software
Internet Key Exchange (IKE) is a key management protocol standard that is used in conjunction with the
IP Security (IPSec) standard. IPSec is a feature that provides robust authentication and encryption of IP
packets.
IKE is a hybrid protocol that implements the Oakley key exchange and the Skeme key exchange inside
the Internet Security Association and Key Management Protocol (ISAKMP) framework. (ISAKMP,
Oakley, and Skeme are security protocols implemented by IKE.)
IPSec can be configured without IKE, but IKE enhances IPSec by providing additional features,
flexibility, and ease of configuration for the IPSec standard.
This module describes how to implement IKE on the Cisco IOS XR Software.
For a complete description of the IKE commands used in this chapter, see the Internet Key Exchange
