For descriptions of MPLS-TP provisioning and inventory interfaces, see the following sections: 

• 

• 

The MPLS-TP entity is characterized as follows: 

•  Has two endpoints. 
•  Has one or two bidirectional Label Switched Path (LSP) pairs between the endpoints. If there 

are two pairs, then one is the working path and the second is the protected path. 

•  The bidirectional LSPs in a pair are congruent. Bidirectional LSPs follow the same path in 

both directions. 

•  The tunnel can be configured with bandwidth. However, unlike MPLS-TE, there is no 

bandwidth reservation or preemption on the NE. Use the show command to view the 
configured bandwidth. Any bandwidth reservation must be handled within the NMS. 

•  Bidirectional Forwarding Detection (BFD) can be configured to monitor any of the 

bidirectional LSP pairs. 

•  MPLS-TP tunnel is used to carry pseudowires. Pseudowires or PW segments are explicitly 

configured to use a particular MPLS-TP tunnel using a given PW-CLASS configuration. 

Figure 4-4 shows a typical MPLS-TP Tunnel.
