Different conceptual models of diff-serv tunneling that either conceal intermediate
LSP nodes from diff-serv operations or render the MPLS network transparent to the
diff-serv operations
Different strategies to set the EXP bits in the shim header to modify or maintain the
traffic class/color combination of traffic
Mapping of traffic behavior aggregates to corresponding per-hop behaviors so that
traffic can be differentially switched to the appropriate LSPs to meet your network
objectives
To configure MPLS for differentiated services:
Configure MPLS to use the pipe or uniform model of tunneling for differentiated services.
See "Configuring the Tunneling Model for Differentiated Services" on page 304.
Configure EXP bits for differentiated services.
See "Configuring EXP Bits for Differentiated Services" on page 304.
Configure differentiated services in a sample topology.
See "Example Differentiated Services Application and Configuration" on page 305.
Classify traffic In a differentiated services domain.
See "Classifying Traffic for Differentiated Services" on page 307.
The JunosE Software supports both the pipe model and the uniform model for tunneling
with the mpls tunnel-model command. The router also provides a way to implement
the functionality of the short pipe model for IP packets.
To specify whether MPLS uses the pipe or uniform model of tunneling for differentiated
services:
Issue the mpls tunnel-model command.
host1(config)#mpls tunnel-model uniform

To set the initial value of the EXP bits to the UPC value associated with the packets:
Issue the mpls copy-upc-to-exp command.
host1(config)#mpls copy-upc-to-exp
