show mpls label usage label-range
Syntax
show mpls label usage label-range <block-label-range range-start range-end> <dynamic-label-range range-start range-end> <label-limit label-limit value> <lsi-label-range range-start range-end> <static-label-range range-start range-end>
Description
There are four different label spaces currently
used in MPLS—namely LSI, dynamic, block, and static. Each label
space has a fixed number and cannot grow beyond the fixed value. Using show mpls label usage label-range
command, the administrator
can monitor the available labels in each label space and the applications
that are using the labels. Based on the availability of labels, the
administrator can decide to stop any service and free some labels
or use other service where the labels are available.
Starting in Junos OS Release 17.2, you can configure the enhanced-ip
command, which is supported on platforms using
Modular Port Concentrators (MPCs) equipped with Junos Trio chipsets.
You can also separate the MPLS labels used for different label spaces
which provides more flexibility and scalability.
When you set each member router’s network services to enhanced-ip
, only MPC or Modular Interface Cards (MICs) modules
and Multiservices Dense Port Concentrator (MS-DPC) modules are powered
on in the chassis. Non-service DPCs do not work with enhanced IP network
services.

Total |
Indicates the total label space available. |
Available |
Indicates the number of freely available labels and also the percentage of the label space available. |
Applications |
Indicates the applications that use the MPLS label spaces. |
Effective Ranges |
Indicates actual ranges in use, which can be different from configured ranges, if conflicting with label already allocated. |

Sample Output
show mpls label usage label-range
With the enhanced-ip
command enabled on the
supported device, you get the following output.
