The Junos OS 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 OS 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 OS 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 OS to monitor the protocol traffic passing through the router and to troubleshoot
protocol and network connectivity problems.
For additional information about the Junos OS, including its security features and a list
of the industry standards it supports, see the Junos OS System Basics Configuration Guide.
For complete information about configuring the software, including examples, see the
Junos OS configuration guides.
NOTE: The router module supports Release 5.2 and later versions of the
Junos OS.
