Configure Differentiated-Services-Aware Traffic Engineering for LSPs
You must configure the differentiated services domain (see Configure Differentiated-Services-Aware Traffic Engineering) before you can enable differentiated-services-aware traffic engineering for LSPs. The differentiated services domain provides the underlying class types and corresponding traffic engineering classes that you reference in the LSP configuration. The traffic engineering classes must be configured consistently on each router participating in the differentiated services domain for the LSP to function properly.

NOTE: You must configure either MAM or RDM as the bandwidth model when you configure differentiated-services-aware traffic engineering for LSPs. See Configure the Bandwidth Model. |
The actual data transmitted over this differentiated services domain is carried by an LSP. Each LSP relies on the EXP bits of the MPLS packets to enable differentiated-services-aware traffic engineering. Each LSP can carry traffic for a single class type.
All the routers participating in the LSP must be Juniper Networks routing platforms running JUNOS software Release 6.3 or later. The network can include routers from other vendors and Juniper Networks routers running earlier versions of the JUNOS software. However, the differentiated-services-aware traffic engineering LSP cannot traverse these routers.

NOTE: You cannot simultaneously configure multiclass LSPs and differentiated-services-aware traffic engineering LSPs on the same router. |
To enable differentiated-services-aware traffic engineering for LSPs, you need to configure the following:
