EXP Value Imposition Guidelines and Restrictions

set mpls experimental imposition 3
Use the set mpls experimental imposition command during label imposition. This command sets
the MPLS EXP field on all imposed label entries.
The set mpls experimental imposition command is supported only on input interfaces
(imposition).
The set mpls experimental imposition command does not mark the EXP value directly; instead, it
marks the internal DSCP that is mapped to EXP through the internal DSCP-to-EXP global map.
It is important to note that classification (based on the original received IP header) and marking
(done to the internal DSCP) do not distinguish between IP-to-IP traffic and IP-to-MPLS traffic. The
commands that you use to mark IP ToS and mark EXP have the same result as when you mark the
internal DSCP.
To set the pushed label entry value to a value different from the default value during label
imposition, use the set mpls experimental imposition command.
