Conti vity 251 ABOT D eployment
1. Introduction
This document proposes a method for using the Web GUI to effectively and economically deploy
large quantities of Asymmetric Branch Office Tunnels (ABOT) between Contivity 251 (C251)
switches located in various branch offices to a Contivity gateway in a Central Office (CO). See
Figure 1 for topology.
The method takes the advantage of the unique feature of "Client Emulation" in C200 series to
allow non-technical end-users to create IPSec VPN user tunnels between C251 and Contivity
gateway in CO. The user tunnels are then used by technical personal in CO to gain controls of
remote C251 for further downloading prepared configuration files in order to complete the
complex ABOT configurations.
For simplicity, the terms of "Contivity" and "Contivity Secure IP Services Gateway" are used
interchangeably in this document.
