Routers in Cloud7 enable network traffic routing between different subnets and external networks. They serve as essential components for managing communication between private and public networks. This guide provides detailed instructions on listing, creating, editing, deleting routers, and managing interfaces and routes.

Routers are critical for network connectivity, external communication, and traffic routing within OpenStack environments. By following this guide, users can efficiently create, manage, and configure routers, interfaces, and routes to build an optimized cloud network.
