Technical Summary
This document describes Multi-Segment Pseudowire (MS-PW) protection
scenarios in which the pseudowire redundancy is provided on the
Switching-PE (S-PE). Operations of the S-PEs which provide PW
redundancy are specified in this document. Signaling of the
preferential forwarding status as defined in [RFC 6870] is reused.
This document does not require any change to the T-PEs of MS-PW.
Working Group Summary
There was nothing particularly unusual in the progress of the draft. The document
originated in the PWE3 working group and moved to the PALS working group when PWE3
was concluded in November 2014. The primary discussion in PWE3 was around clarification
of the new procedures at the S-PE.
Document Quality
There are multiple implementations of PW redundancy, based on RFC6718 and RFC6870.
This document reuses the procedures in those RFCs in the context of an S-PE.
The document has also been widely reviewed by the original authors and
contributors to those RFCs. I do not have any concerns with the quality of the
document.
