VPN configuration

[Chad Schieken]

Jeanne,

Keep in mind that when you use an Internet VPN you can get no SLA to
guarantee uptime or packet delivery. So the question becomes, what do you
do when the Internet can't get the packets from the store to the date center...

Since you'll have the circuit costs anyway you may not realize any $$$
benefit. Normally the cost savings with a VPN come from 1. Already
having/needing Internet access and 2. not having to seperate circuits/PVCs
for each location.

Not saying it won't work or save money, just that you need to be very clear
on your design criteria.


later...
