Cisco ASR 900 Series User Manual

CHAPTER 2
MPLS Transport Profile
This chapter is not applicable on the ASR 900 RSP3 Module.Note
Multiprotocol Label Switching (MPLS) Transport Profile (TP) enables you to create tunnels that provide
the transport network service layer over which IP and MPLS traffic traverses. MPLS-TP tunnels enable a
transition from Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH)
time-division multiplexing (TDM) technologies to packet switching to support services with high bandwidth
requirements, such as video.

•
Multiprotocol Label Switching Transport Profile (MPLS-TP) penultimate hop popping is not supported.
Only ultimate hop popping is supported, because label mappings are configured at the MPLS-TP endpoints
•
IPv6 addressing is not supported.

Local switching with Any Transport over MPLS (AToM) pseudowire as a backup is not supported.
•
L2VPN pseudowire redundancy to an AToM pseudowire by one or more attachment circuits is not
supported.
•
Pseudowire ID Forward Equivalence Class (FEC) type 128 is supported, but generalized ID FEC type
129 is not supported
