Introduction
This document provides a sample configuration for VPN load balancing on a Content Switching Module
(CSM). VPN load balancing is a mechanism that intelligently distributes VPN sessions along a set of VPN
concentrators or VPN head−end devices. VPN load balancing is implemented for these reasons:
(CSM). VPN load balancing is a mechanism that intelligently distributes VPN sessions along a set of VPN
concentrators or VPN head−end devices. VPN load balancing is implemented for these reasons:
to overcome performance or scalability limitations on VPN devices; for example, packets per second,
connections per second, and throughput
connections per second, and throughput

Prerequisites
Requirements
Ensure that you meet these requirements before you attempt this configuration:
Implement Reverse Route Injection (RRI) at the head−end devices, to propagate the routing
information from the spokes automatically.
information from the spokes automatically.
