In this video, Keith Barker covers dynamic multipoint VPNs. DMP VPNs are becoming increasingly popular, especially among companies that have multiple geographically separated branches and offices. See what makes a DMP VPN awesome, how they operate, and why they're so valuable.
The idea of a virtual private network is probably familiar to most IT personnel. When you want to treat the local networks of separated offices like they're connected to a local network, a VPN can help do that. It starts by building a generic router encapsulation (GRE) tunnel between any branch routers and the headquarters router - basically just a logical pipe across the internet. You can even secure the traffic that passes through that pipe with IPsec.
But when you need the branches to communicate directly with one another, a basic configuration may not work. Since any traffic from one branch to the other passes through the headquarters router, eventually you'll probably reach unsustainable levels of overhead and bandwidth. A dynamic multi-point VPN alleviates that concern, enabling the first branch router to build a direct GRE IPsec connection between itself and the other router, with the direction and guidance of the headquarters router.
