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.

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]

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.

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
    Tunnel1032 (traffic share 10000, nexthop 3.3.3.3)

nexthop

MPLS traffic engineering tailend IP address of the tunnel.

absolute metric

(Optional) Restricts the display to tunnels with the indicated role (all, head, middle, tail, or remote).

all

(Optional) Displays all tunnels.

head

(Optional) Displays tunnels with their heads at this router.

middle

(Optional) Displays tunnels with their midpoints at this router.

tail

(Optional) Displays tunnels with their tails at this router.

remote

(Optional) Displays tunnels with their heads at another router; this is a combination of the middle and tail keyword values.

up

(Optional) Displays tunnels if the tunnel interface is up. Tunnel midpoints and tails are typically up or not present.

down

(Optional) Displays tunnels that are down.

name string

(Optional) Displays tunnels with the specified name. The tunnel name is derived from the interface description, if specified; otherwise, it is the interface name. The tunnel name is included in the signalling message so it is available at all hops.

suboptimal constraints none

(Optional) Displays tunnels whose path metric is greater than the shortest unconstrained path. Selected tunnels have a longer path than the IGP's shortest path.

suboptimal constraints current

(Optional) Displays tunnels whose path metric is greater than the current shortest path, constrained by the tunnel's configured options. Selected tunnels would have a shorter path if they were reoptimized immediately.

suboptimal constraints max

(Optional) Displays tunnels whose path metric is greater than the current shortest path, constrained by the tunnel's configured options, and considering only the network's capacity. Selected tunnels would have a shorter path if no other tunnels were consuming network resources.

interface in phys-intf

(Optional) Displays tunnels that use the specified input interface.

interface out phys-intf

(Optional) Displays tunnels that use the specified output interface.

interface phys-intf

(Optional) Displays tunnels that use the specified interface as an input or output interface.

brief

(Optional) Specifies one line per tunnel.
