Cisco Cisco IOS Software Release 12.0(23)S

To specify which MPLS experimental bit values for a VC class can be mapped to a VC bundle and thus 
applied to all VC members of that bundle, use the mpls experimental command in the appropriate 
configuration mode. To remove the experimental bit values, use the no form of this command. 

mpls experimental {other | range}

no mpls experimental {other | range}

Defaults to other, that is, any precedence levels in the range from 0 to 7 that are not explicitly configured.

VC-class configuration (for a VC class)

Bundle-vc configuration (for ATM VC bundle members)

This command is available only when MPLS forwarding has been enabled on the subinterface through 
the use of the tag-switching ip command. In this regard, it is a companion command to the precedence 
(VC bundle) command, which is used on subinterfaces where MPLS forwarding is not enabled.

To use this command in vc-class configuration mode, first enter the vc-class command in global 
configuration mode.

To use this command to configure an individual bundle member in bundle-vc configuration mode, first 
enter the bundle command to enact bundle configuration mode for the bundle to which you want to add 
or modify the VC member to be configured. Then, use the pvc-bundle command to specify the VC to 
be created or modified and enter bundle-vc configuration mode. 

VCs in a VC bundle are subject to the following configuration inheritance guidelines (listed in order of 
next highest precedence):

VC configuration in bundle-vc mode

Bundle configuration in bundle mode (with effect of assigned vc-class configuration)

Subinterface configuration in subinterface mode

(Optional) Any MPLS experimental bit values in the range from 0 to 7 that 
are not explicitly configured. 

(Optional) A single MPLS experimental bit value specified as a number, or 
a range of MPLS experimental bit value, specified as a hyphenated range. 

11.1(22)CC

This command was introduced.

12.0(3)T

This command was integrated into Cisco IOS Release 12.0(3)T. This 
command was extended to configure precedence levels for a VC member of 
a bundle.

12.0(23)S

This command was integrated into Cisco IOS Release 12.0(23)S.
