Configures the number of labels that are reserved for specifying the incoming label for static LSPs and static pseudowires.
| labels |
Specifies that labels are reserved to specify the incoming label for static LSPs and static pseudowires. |
| max-static |
Specifies the number of labels that are reserved to specify the incoming label for static LSPs and static PWs. |
| max_static-labels |
Specifies the value for the maximum number of static labels. |
The default static label range size is 100.
Use this command to configure the number of labels that are reserved for specifying the incoming label for static LSPs and static PWs. The static label range generally starts at 16 and the default static label range size is 100. This means that the default static label range is 16 through 115 and can be allocated for either incoming (both transit and egress) static LSPs, or incoming static PWs. The maximum static label_range_size is equal to the incoming label table size – 100 labels for signaling. 960 labels are reserved for L3VPNs. The maximum number of labels available for static configuration is 7116, since at least 100 of those labels are reserved for dynamic signaling.
Since these values vary per-platform, use the show mpls label usage command to see details about label usage and platform capability. The minimum static label range size is 0.
Note
MPLS (Multiprotocol Label Switching) must be disabled when issuing this command. If MPLS is enabled, an error message is displayed and the command has no affect. All other labels, including outgoing labels for static LSPs and PWs and signaled labels used by RSVP-TE and LDP, are allocated out of the dynamic label space.The following example illustrates how to configure MPLS max-static labels, and how to display them:
