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 Configuration Guide . For information about configuring peer relationships between logical systems, see Junos OS Services Interfaces Configuration Guide .

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;}}}}
