Each J-series Services Router runs the JUNOS Internet software on its general-purpose processors. Designed for the large production networks typically supported by Internet service providers (ISPs), the JUNOS software includes processes for Internet Protocol (IP) routing and for managing interfaces, networks, and the router chassis.
The JUNOS Internet software runs on the Routing Engine. The Routing Engine kernel coordinates communication among the JUNOS software processes and provides a link to the Packet Forwarding Engine.
With the J-Web interface and the command-line interface (CLI) to the JUNOS software, you configure the routing protocols that run on the Services Router and set the properties of its network interfaces. After activating a software configuration, use either user interface to monitor the protocol traffic passing through the router, manage operations, and diagnose protocol and network connectivity problems.
