1. An Enterprise VPN > Implementation

Implementation

Once the high-level design was created, reviewed, and approved by the CEO, the actual implementation of the new network was undertaken. The plan used a three-phase approach. In the first phase, a prototype network was created that verified the operation of the design. In the second phase, the equipment was installed onsite and interconnected. In the final phase, the new network was cut into the existing network.

Prototype Phase

All the Juniper Networks equipment was delivered to the main location, unpacked, and powered up in a lab environment. With the use of routing instances, all the devices of the network were created and interconnected. The J-series routers are equipped with flow-based services and full stateful security services, so these were configured as the firewalls as well as the local routers (all in one box). The router for the backup servers (Nashville) was divided into the local router, the Internet, and the AT&T VPN. Finally, the main routers were configured as themselves. One of the remote locations was repurposed to act as the main location firewall.
