Use of Multipath with MPLS-TP and MPLS
Outer Cape Cod Network
Many MPLS implementations have supported multipath techniques and many MPLS deployments have used multipath techniques, particularly in very high bandwidth applications, such as provider IP/MPLS core networks. MPLS-TP has strongly discouraged the use of multipath techniques. Some degradation of MPLS-TP OAM performance cannot be avoided when operating over many types of multipath implementations. Using MPLS Entropy label, MPLS can LSP can be carried over multipath links while also providing a fully MPLS-TP compliant server layer for MPLS-TP LSP. This document describes the means of supporting MPLS as a server layer for MPLS-TP. The use of MPLS-TP LSP as a server layer for MPLS LSP is also discussed.
