We will begin by reviewing the typical site-to-site IPsec model over a dedicated circuit between two endpoints, then discuss some of the design implications as that dedicated circuit grows to include an entire routed domain. We will discuss 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.
