Scaling and Optimizing IPsec VPNs

Chapter 6, "Deploying Site-to-Site IPsec VPNs," introduced IPsec VPNs. This chapter looks at how to scale IPsec VPNs using technologies such as Tunnel Endpoint Discovery (TED) and Dynamic Multipoint VPN (DMVPN), how IPsec VPNs can support quality of service (QoS), and how to avoid performance degradation caused by IPsec packet fragmentation.
