MP-161
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
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 MPLS EXP level):
• VC configuration in bundle-VC mode
• Bundle configuration in bundle mode (with the effect of assigned VC class configuration)
• Subinterface configuration in subinterface mode
Note If you are using an ATM interface, you must configure all MPLS EXP levels (ranging from 0 to 7) for
the bundle. For this configuration, Cisco recommends configuring one member of the bundle with the
mpls experimental other command. The other keyword defaults to any MPLS EXP level in a range
from 0 to 7 that is not explicitly configured.
Examples The following example configures a class named control-class that includes an mpls experimental
command that, when applied to a bundle, configures all VC members of that bundle to carry MPLS EXP
level 7 traffic. Note that VC members of that bundle can be individually configured with the mpls
e
xperimental command at the bundle-vc level, which would supervene.
vc-class atm control-class
mpls experimental 7
The following example configures a permanent virtual circuit (PVC) 401, named control-class, to carry
traffic with MPLS EXP levels in the range of 4 to 2, overriding the level mapping set for the VC through
VC-class configuration:
pvc-bundle control-class 401
mpls experimental 4-2
