Uniform Model

The uniform model of tunneling renders MPLS transparent to the differentiated services operation. From the diff-serv perspective, it is as if MPLS is not used. In the uniform model, if traffic conditioning is applied somewhere along the LSP, the EXP bits of the inner header must be changed at the egress when the inner header becomes the outer header (because of the pop of the outer label).

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
