Usage Guidelines
When two label switch routers (LSRs) establish an LDP session, they negotiate parameters for the session, such as the range of virtual path identifiers (VPIs) and virtual channel identifiers (VCIs) that will be used as labels.
This command displays the MPLS ATM capabilities negotiated by LDP or the Tag Distribution Protocol (TDP).

Field

Description
|
VPI Range
|
Minimum and maximum numbers of VPIs supported on this interface.
|
VCI Range
|
Minimum and maximum numbers of VCIs supported on this interface.
|
Alloc Scheme
|
Indicates the applicable allocation scheme, as follows:
• UNIDIR—Unidirectional capability indicates that the peer can, within a single VPI, support binding of the same VCI to different prefixes on different directions of the link.
• BIDIR—Bidirectional capability indicates that within a single VPI, a single VCI can appear in one binding only. In this case, one peer allocates bindings in the even VCI space, and the other in the odd VCI space. The system with the lower LDP identifier assigns even-numbered VCIs.
The negotiated allocation scheme is UNIDIR, only if, both peers have UNIDIR capability. Otherwise, the allocation scheme is BIDIR.
Note These definitions for unidirectional and bidirectional are consistent with normal ATM usage of the terms; however, they are exactly opposite from the definitions for them in the IETF LDP specification.
|
Odd/Even Scheme
|
Indicates whether the local device or the peer is assigning an odd- or even-numbered VCI when the negotiated scheme is BIDIR. It does not display any information when the negotiated scheme is UNIDIR.
|
VC Merge
|
Indicates the type of virtual circuit merge support available on this interface. There are two possibilities, as follows:
IN—Indicates the input interface merge capability. IN displays the following values:
• EN—The hardware interface supports virtual circuit merge, and virtual circuit merge is enabled on the device.
• DIS—The hardware interface supports virtual circuit merge and virtual circuit merge is disabled on the device.
• NO—The hardware interface does not support virtual circuit merge.
OUT—Indicates the output interface merge capability. OUT displays the same values as the input merge side.
The virtual circuit merge capability is meaningful only on ATM switches. This capability is not negotiated.
|
Negotiated
|
Indicates the set of options that both LDP peers have agreed to share on this interface. For example, the VPI or VCI allocation on either peer remains within the negotiated range.
|
Local
|
Indicates the options supported locally on this interface.
|
Peer
|
Indicates the options supported by the remote LDP peer on this interface.

Usage Guidelines
The show mpls ip binding command displays label bindings learned by LDP or Tag Distribution Protocol (TDP).
A request can specify that the entire database be displayed, that a summary of entries from the database be displayed, or that the display be limited to a subset of entries. The subset can be limited according to any of the following:
•

•
Input or output label values or ranges
•
Neighbor advertising the label
•
Interface for label bindings of interest (LC-ATM only)
•
Generic (non-LC-ATM) label bindings

The status of the VC. The status can be one of the following:
UP—The VC is in a state where it can carry traffic between the two VC endpoints. A VC is up when both imposition and disposition interfaces are programmed.
• The disposition interface is programmed if the VC has been configured and the client interface is up.
• The imposition interface is programmed if the disposition interface is programmed and a remote VC label and an Interior Gateway Protocol (IGP) label exist. The IGP label can be an implicit null in a back-to-back configuration. (An IGP label means there is a label switched path [LSP] to the peer.)
DOWN—The VC is not ready to carry traffic between the two VC endpoints.
ADMIN DOWN—The VC has been disabled by a user.
|
Tunnel label
|
An IGP label used to route the packet over the MPLS backbone to the destination router with the egress interface. The first part of the output displays the type of label. The second part of output displays the route information.
The tunnel label information can display any of the following states:
imp-null: The provider core (P) router is absent and the tunnel label will not be used. Alternatively, imp-null can signify traffic engineering tunnels between the PE routers.
unassigned: The label has not been assigned.
no route: The label is not in the routing table.
no adjacency: The adjacency for the next hop is missing.
not ready, no route: An IP route for the peer does not exist in the routing table.
not ready, not a host table: The route in the routing table for the remote peer router is not a host route.
not ready, CEF disabled: CEF is disabled.
not ready, LFIB disabled: The MPLS switching subsystem is disabled.
not ready, LFIB entry present: The tunnel label exists in the LFIB, but the VC is down.
|

Usage Guidelines
You can use the mpls label range command to configure a range for local labels that is different from the default range. If the newly configured range does not overlap the current range, then the new range will not take effect until the router is reloaded. In this situation, the show mpls label range command displays both the label range currently in use and the label range that will be in use following the next router reload.
Examples
In the following example, the use of the show mpls label range command is shown before and after the mpls label range command is used to configure a label range that does not overlap the starting label range.
Router# show mpls label range
Downstream label pool: Min/Max label: 16/100000
Router# configure terminal
Router(config)# mpls label range 200 120000
% Label range changes will take effect at the next reload.
Router# show mpls label range
