You can partition a single physical router into multiple logical routers that perform independent routing tasks. Because logical routers perform a subset of the tasks once handled by the physical router, logical routers offer an effective way to maximize the use of a single routing platform.
Logical systems perform a subset of the actions of a physical router and have their own unique routing tables, interfaces, policies, and routing instances. A set of logical routers within a single router can handle the functions previously performed by several small routers.
You can configure Layer 2 VPNs, Layer 3 VPNs, VPLS, and Layer 2 circuits within a logical system. For more information on logical routers, see the JUNOS Routing Protocols Configuration Guide.

Note: Beginning with JUNOS software Release 9.3, the logical router feature has been renamed logical system. All configuration statements, operational commands, show command outputs, error messages, log messages, and SNMP MIB objects that contain the string logical-router or logical-routers have been changed to logical-system and logical-systems, respectively. |
