Configuring Logical System Interface Properties

With Junos OS, you can partition a single physical router into multiple logical devices that perform independent routing tasks. Because logical systems perform a subset of the tasks once handled by the physical router, logical systems offer an effective way to maximize the use of a single router.

You can include the following logical system statements:

[edit logical-systems logical-system-name]
interfaces interface-name {unit logical-unit-number {logical-interface-statements;}}
policy-options {policy-options-statements;}
protocols {protocols-statements;}
routing-instances {routing-instances-statements;}
routing-options {routing-options-statements;}

For an overview of logical systems, see the Junos OS Feature Guides. For detailed information about logical system configuration, see the Junos OS Routing Protocols Library for Routing Devices. For information about configuring peer relationships between logical systems, see Junos OS Services Interfaces Library for Routing Devices.

To configure interface properties of a logical system, you must include the following statements at the [edit logical-systems logical-system-name] hierarchy level:

[edit logical-systems logical-system-name]
interfaces interface-name {unit logical-unit-number {logical-interface-statements;}}

Example: Configuring Logical System Interface Properties

Configure a logical system’s interface properties:

[edit interfaces t3-0/0/1]description “ Physical interface to be partitioned into multiple logical systems”;[edit logical-systems 1-on-t3-0/0/1]
interfaces t3-0/0/1 {unit 1 {family inet {address 10.0.0.1/32 {destination 10.0.0.2;}}}}
