MPLS-TP is supported on PWs with static labels. The provisioning model supports RFC6370-style PW path identifiers for MPLS-TP PWs.
MPLS-TP PWs reuse the static PW provisioning model of previous SR OS releases. Including the use of the PW-switching key work to distinguish an S-PE. Therefore, the primary distinguishing feature for an MPLS-TP PW is the ability to configure MPLS-TP PW path identifiers, and to support MPLS-TP OAM and static PW status signaling.
The system can perform the role of a T-PE or an S-PE for a PW with MPLS-TP.
A spoke SDP with static PW labels and MPLS-TP identifiers and OAM capabilities can use an SDP that uses either an MPLS-TP tunnel, or that uses regular RSVP-TE LSPs. The control word is supported for all MPLS-TP PWs.
