Abstract

IPsec Virtual Private Network (VPN) is widely used by enterprises to interconnect their geographical dispersed branch office locations across IP Wide Area Network (WAN) or the Internet, especially in the Software-Defined-WAN (SD-WAN) era. To fully utilize the bandwidth available in IP WAN or the Internet, load balancing of traffic between different IPsec VPN sites over Equal Cost Multi-Path (ECMP) and/or Link Aggregation Group (LAG) is attractive to those enterprises deploying IPsec VPN solutions. This document defines a method to encapsulate IPsec Encapsulating Security Payload (ESP) packets over UDP tunnels for improving load-balancing of IPsec ESP traffic.
