For more background on IPsec fundamentals, see my IPsec quick and dirty article.įor simplicity, we'll use a static pre-shared key for ISAKMP authentication (which will be defined in step four).į1(config-isakmp-policy)# authentication pre-shareį1(config-isakmp-policy)# encryption aes-256 ISAKMP is used to establish the initial asymmetrically encrypted channels between the two endpoints so that they can securely negotiate a pair of one-way IPsec security associations (SAs). Here we'll see how to configure a simple L2L VPN as pictured in the below topology in a few simple steps. LAN-to-LAN VPNs are typically used to transparently connect geographically disparate LANs over an untrusted medium (e.g. In the case of a mixed order, you still do not pay shipping charges for qualifying items when they are shipped via ground delivery however, you are responsible for paying shipping charges for non-qualifying items in a mixed order.Today we're going to look at LAN-to-LAN VPNs using the pair of ASA 5505s in the community lab.
