In a nutshell, IPSEC is encryption methodology open standard. IPSEC SAs can be configured using IKE or manual keying. IKE saves time and manual work in hub and spoke configurations. It is an algorithm that uses policy to determine matching parameters with the other side. In absence of IKE, you would have to configure each parameter manually on all participating routers and clients.
IKE is called phase I negotiation, which ensures that peer is who it says it is. -Keyur Shah- CCIE# 4799 (Security; Routing and Switching) CSS1,CCNA,CCDA,SCSA,SCNA,MCT,MCSE,MCP+I,MCP,CNI,MCNE,CNE,CNA Hello Computers "Say Hello to Your Future!" http://www.hellocomputers.com Toll-Free: 1.877.794.3556 International: 1.510.795.6815 Eurpoe: +(44)20 7900 3011 Fax: 1.510.291.2250 -----Original Message----- From: Hunt Lee [mailto:[EMAIL PROTECTED]] Sent: Friday, October 19, 2001 6:16 PM To: [EMAIL PROTECTED] Subject: IPSec and IKE [7:23599] Can anyone please explain to me what is the difference between IPSec and IKE? I understand that IP Sec is just IP Security, which provides IP network layer encryption and authentication to end-to-end security on an infrastructure, but what's IKE? I read the Cisco MCNS book from Chapter 15 to 17 many times, yet I'm still very confused. Any help will be greatly appreciated.
