Configuring Logical System Interface Properties
With JUNOS software, you can partition a single physical routing platform into multiple logical devices that perform independent routing tasks. Because logical systems perform a subset of the tasks once handled by the physical routing platform, logical systems offer an effective way to maximize the use of a single router platform.
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 Feature Guide. For detailed information about logical system configuration, see the JUNOS Routing Protocols Configuration Guide. For information about configuring peer relationships between logical systems, see JUNOS 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;
- }
- }
- }
- }
