IPsec Virtual Private Network Fundamentals

Chapter 9. Solutions for Remote-Access VPN High Availability As workforces become more virtualized and mobile, the growth in Remote-Access Virtual Private Network (RAVPN) deployments increases, which also drives the need for IPsec High Avail...

IPsec RAVPN Concentrator High Availability Using Virtual Interfaces for Tunnel Termination IPsec RAVPN Concentrator HA can be achieved using a virtual interface protocol such as Hot Standby Router Protocol (HSRP) or Virtual Router Redundancy Proto...

IPsec RAVPN Concentrator HA Using the VCA Protocol VCA has become a very popular means by which to provide Local HA in VPN concentrator cluster designs. In a design that uses VCA, the VPN concentrators participating in the cluster are known as VCA...

IPsec RAVPN Geographic HA Design Options Once the RAVPN has the appropriate amount of resiliency designed into the VPN concentrator cluster, there are several design options that can be selected for VPN clients to take full advantage of the resili...

Summary The availability of a remote access VPN infrastructure is largely centered around the concentration point of RAVPN tunnels. This chapter has focused on presenting designs scenarios that can be used to increase the availability of RAVPN con...
