or prevent the route from being exported altogether. You also can define policies for
redistributing the routes learned from one protocol into another protocol.
VPNs
The Junos OS supports several types of VPNs:
•
Layer 2 VPNs
•
Layer 3 VPNs
•
Interprovider VPNs
•
Carrier-of-Carrier VPNs
Interface Process
The Junos interface process manages the physical interface devices and logical interfaces
in the routing matrix. It implements the Junos OS command-line interface (CLI) commands
and configuration statements that you use to specify interface properties such as location
(FPC location in the routing matrix and PIC location on an FPC), the interface type (such
as SONET/SDH or ATM), encapsulation, and interface-specific properties. You can
configure both interfaces that are currently active and interfaces that might be installed
later.
The Junos interface process communicates with the Packet Forwarding Engine through
the Junos kernel, enabling the Junos OS to track the status and condition of routing matrix
interfaces.
Chassis Process
The Junos chassis process, which runs on all Routing Engines in the routing matrix, allows
you to configure and control the properties of the routing matrix, including conditions
that trigger alarms and clock sources. The chassis process running on the TX Matrix
Routing Engine manages the components in the TX Matrix chassis, and the chassis
process running on each T640 router Routing Engine manages the components in that
router's chassis. All chassis processes running in the routing matrix collectively coordinate
the control of the routing matrix switch fabric.
SNMP and MIB II Processes
The Junos OS supports the Simple Network Management Protocol (SNMP), versions 1,
2, and 3, which provides a mechanism for monitoring the state of the routing matrix. This
software is controlled by the Junos SNMP and Management Information Base (MIB) II
processes, which consist of an SNMP master agent and a MIB II agent, and run on the
TX Matrix Routing Engine.
Management Process
The management process starts all the other Junos OS processes and the CLI when the
router boots. It monitors the running Junos processes and makes all reasonable attempts
to restart any process that terminates.
