show mpls label range

To display the range of local labels available for use on packet interfaces, use the show mpls label range privileged EXEC command.

show mpls label range

Syntax Description

This command has no optional keywords or arguments

Defaults

This command has no default behavior or values.

Command Modes

Privileged EXEC

Command History

Release	Modification
12.0(9)ST	This command was introduced.

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(config)# exit

Router# show mpls label range

Downstream label pool: Min/Max label: 16/100000

   [Configured range for next reload: Min/Max label: 200/120000]

Related Commands

Command	Description

show mpls traffic-eng autoroute

To show tunnels that are announced to the Interior Gateway Protocol (IGP), including interface, destination, and bandwidth, use the show mpls traffic-eng autoroute EXEC command.

show mpls traffic-eng autoroute

Syntax Description

This command has no arguments or keywords.

Defaults

No default behavior or values.

Command Modes

EXEC

Command History

Release	Modification
12.0(5)S	This command was introduced.

Usage Guidelines

The enhanced shortest path first (SPF) calculation of the IGP has been modified so that it uses traffic engineering tunnels. This command shows which tunnels IGP is currently using in its enhanced SPF calculation (that is, which tunnels are up and have autoroute configured).

Examples

The following is sample output from the show mpls traffic-eng autoroute command.

Note that the tunnels are organized by destination. All tunnels to a destination carry a share of the traffic tunneled to that destination.

Router# show mpls traffic-eng autoroute 

MPLS TE autorouting enabled

  destination 0002.0002.0002.00 has 2 tunnels

    Tunnel1021 (traffic share 10000, nexthop 2.2.2.2, absolute metric 11)

    Tunnel1022 (traffic share 3333, nexthop 2.2.2.2, relative metric -3)

  destination 0003.0003.0003.00 has 2 tunnels

nexthop	MPLS traffic engineering tailend IP address of the tunnel.
absolute metric	MPLS traffic engineering metric with mode absolute of the tunnel.
relative metric	MPLS traffic engineering metric with mode relative of the tunnel.
