mpls experimental Command

To configure Multiprotocol Label Switching (MPLS) experimental (EXP) levels for a virtual circuit
(VC) class that can be assigned to a PVC bundle and thus applied to all PVC members of that bundle,
use the mpls experimental command in vc-class configuration mode. To remove the MPLS EXP levels
from the VC class, use the no form of the command.
To configure the MPLS EXP levels for a PVC member of a bundle, use the mpls experimental command
in bundle-vc configuration mode. To remove the MPLS EXP levels from the PVC, use the no form of
the command.

Usage Guidelines for the mpls experimental Command
Assignment of MPLS EXP levels to VC bundle members allows you to create differentiated service
because you can distribute the MPLS EXP levels over the different VC bundle members. You can map
a single level or a range of levels to each discrete VC in the bundle, thereby enabling VCs in the bundle
to carry packets marked with different levels. Alternatively, you can configure a VC with the
mpls experimental other command to indicate that it can carry traffic marked with levels not
specifically configured for it. Only one VC in the bundle can be configured with the mpls experimental
other command to carry all levels not specified. This VC is considered the default VC.
To use this command in vc-class configuration mode, enter the vc-class atm global configuration
command before you enter this command. This command has no effect if the VC class that contains the
command is attached to a standalone VC, that is, if the VC is not a bundle member.
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.
