Mapping association between EXP bits and traffic class/color combination is done
automatically by the JunosE Software at the appropriate routers along the path.
Figure 65: Associations Between PHB ID, EXP Bits, and Traffic
Classes/Colors
Figure 66 on page 311 shows the operations performed at ingress, transit, and egress
systems during signaled mapping sessions.

To define a policy rule that sets the EXP bits in packets to which the policy is applied:
•
Issue the mark-exp command.
host1(config-policy-list)#mark-exp 5 classifier-group claclEXP precedence 32
To create or modify an MPLS classifier control list to match on traffic class/color
combination or EXP bits:
•
Issue the mpls classifier-listcommand.
