tunnel mpls traffic-eng exp
To specify the experimental (EXP) bits that will be forwarded over a member tunnel that is part of the
Class-Based Tunnel Selection (CBTS) bundle, use the tunnel mpls traffic-eng exp command in
interface configuration mode. To disable forwarding of the EXP bits, use the no form of this command.

Command History
Usage Guidelines You should enter the t
unnel mpls traffic-eng exp command to specify the EXP bits for at least one
member tunnel.
With the t
unnel mpls traffic-eng exp command, you can configure each tunnel with any of the
following:
• No EXP-related information
• One or more EXP values for the tunnel to carry (list-of-exp-values argument)
• All EXP values not currently allocated to any up tunnel (default keyword)
• One or more EXP values for the tunnel to carry, and the property that allows the carrying of all EXP
values not currently allocated to any up tunnel (list-of-exp-values default argument-keyword pair)
The de
fault keyword allows you to avoid explicitly listing all possible EXP values. You indicate a
preference as to which tunnel to use for certain EXP values, should a tunnel other than the default tunnel
go down.
list-of-exp-values EXP bits allowed for the interface. Enter up to eight EXP values separated
by spa
ces. Values range from 0 to 7. The default is the EXP values that were
no
t configured or a specific member tunnel.
default The member tunnel will forward the packets with the EXP bits that are not
b
eing forwarded by other member tunnels that are part of the same bundle.
