VPNs
The JUNOS soft
ware supports several t ypes of VPNs:
• Layer 2 VPNs—A Layer 2 VPN links a set of sites sharing common routing information,
and whose conn
ectivity is controlled by a collection of policies. A Layer 2 V PN is not
aware of routes w ithin a customer’s network. It simply provides private links between a
customer’s sites over the service provider’s existing public Internet backbone.
• Layer 3 VPNs—A Layer 3 VPN links a set of sites that share common routing
information, and whose connectivity is controlled by a collection of policies. A Layer 3
VPN is aware o
f routes within a customer’s network, requiring more configuration on
the p art of the service provider than a Layer 2 VPN. The sites that make up a Layer 3
VPN are connected over a service provider’s existing public Internet backbone.
• Interprovider VPNs—A n interprovider VPN supplies connectivity b etween two VPNs
in separate autonomous systems ( ASs). This functionality could be used by a VPN
customer wi
th connections to several various ISPs, or different connections to the
same ISP in various geographic regions.
• Carrier-of
-Carrier VPNs—Carrier-of-carrier VPNsallowaVPNserviceprovidertosupply
VPN service to a customer who is also a service provider. The latter service provider
supplies Internet or VPN service to an end customer.
Interface Process
The JUNOS interface process manages the physical interface devices and logical interfaces
on the router. It implements the JUNOS command-line interface (CLI) commands and
configura
tion statements that you use to specify interface properties such as location (FPC
location in the FPC card cage and PIC location on an FPC), the interface type (such as
SONET/SDH or ATM), encapsulation, and interface-specific properties. You can configure
both inter
faces that are currently active and interfaces that might be installed later.
The JUNOS interface process c ommunicates with the interface process in the Packet
Forwardi
ng Engine through the JUNOS kernel, enabling the JUNOS Internet software to track
the status and condition of router interfaces.
Chassis Process
The JUNOS chassis process allows you to configure and control the properties of the
router, including conditions that trigger alarms and clock sources. The chassis process
communic
ates directly with a chassis process in the JUNOS kernel.
SNMP and MIB II Processes
The JUNO
S Internet software supports the Simple Network Management Protocol (SNMP),
versions 1, 2, and 3, which provides a mechanism for monitoring the state of the router.
This software is controlled by the JUNOS SNMP and Management Information Base (MIB) II
process
es, which consist of an SNMP master agent and a MIB II agent.
