JUNOS Internet Software Overview

Routing Engine Software Components

The JUNOS Internet software is especially designed for the large production networks
typically supported by Internet Service Providers (ISPs). It incorporates Internet
Protocol (IP) routing software and software for management of interfaces, networks,
and the router chassis.
The JUNOS Internet software runs on the Routing Engine. The software consists of
processes that support Internet routing protocols, control the router's interfaces and
the router chassis itself, and provide an interface for system management. The
processes run on top of a kernel that coordinates the communication among processes
and has a direct link to the Packet Forwarding Engine software.
Use the JUNOS Internet software to configure the routing protocols that run on the
router and the properties of router interfaces. After you have activated a software
configuration, use the JUNOS Internet software to monitor the protocol traffic passing
through the router and to troubleshoot protocol and network connectivity problems.
For additional information about the JUNOS Internet software, including its security
features and a list of the industry standards it supports, see the JUNOS System Basics
Configuration Guide. For complete information about configuring the software,
including examples, see the JUNOS Internet software configuration guides.
NOTE: The router supports Release 6.1 and later versions of the JUNOS Internet
software.
