Basic IPsec VPN topologies and configurations - from IPsec Virtual Private Network Fundamentals

In this chapter: The author provides a review of several common deployments of IPsec virtual private networks (VPNs). He covers typical site-to-site IPsec model over a dedicated circuit between two endpoints, then discusses some of the design implications as that dedicated circuit grows to include an entire routed domain. Learn about aggregation of many site-to-site IPsec VPNs at an aggregation point, or hub IPsec router, in a standard hub-and-spoke design and extend the IPsec aggregation concept to include Remote Access VPN (RAVPN) design considerations.
