An edge router is simply a router that connects the network you control to a network that you don't. In most cases, it is the router that's connected directly to your internet connection. This is in opposition to a core router, which is a router that routes between multiple networks that are all under your control. An edge router is generally a lower-end router, as it tends not to do much beyond pass traffic, and generally to a circuit that has a relatively low bandwidth. Edge routers are sometimes combined with firewalls, NATs, and VPN endpoints, but I'm not really sure you'd still call it an edge router at that point. | ||||
