To ensure that your connection to the INX is easy, as well as secure, we have created a set of templates for the configuration of various types of hardware in common use at the exchange point.

Although we do filter specific types of Layer-2 frames, we still encourage peers to keep their ports clean, and may insist on this before moving you out of quarantine.

Connection via a router

 We recommend that you use a Layer 3 device to connect to the INXes;  doing so, minimises your risk of creating any unnecessary loops.  Below are some configurations that should help if you connect directly to a router (preferred)
