Framework for IPsec Protected Virtual Links for PPVPNs
Quarry Technologies
This memo explores some choices that arise when IPsec is to be used to implement secure 'virtual links' interconnecting customer premises VPN devices and/or network based virtual routers. The main focus is on the network based cases. Requirements are proposed and some relevant aspects of the IPsec protocol suite are discussed. A number of different protocol architectures for virtual links are then evaluated. This memo is informational in nature; it is intended that it will focus discussion toward a standard in this area.
