It is not clear to me that it will be possible to detect a tunnel failure, at any point in the corresponding tunnel LSP other than tunnel end points, except as a result of a physical port failure.

The following errata report has been submitted for RFC8077, "Pseudowire Setup and Maintenance Using the Label Distribution Protocol (LDP)".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata/eid5243

--------------------------------------
Type: Technical
Reported by: JAYANT BHARDWAJ <jbhardwa@ciena.com>

Section: 6.1

Original Text
-------------
-  Group ID

      An arbitrary 32-bit value that represents a group of PWs that is
      used to create groups in the PW space.  The Group ID is intended
      to be used as a port index or a virtual tunnel index.  To simplify
      configuration, a particular PW Group ID at ingress could be part
      of a Group ID assigned to the virtual tunnel for transport to the
      egress router.  The Group ID is very useful for sending wildcard
      label withdrawals or PW wildcard status Notification messages to
      remote PEs upon physical port failure.

Corrected Text

-  Group ID
 
      An arbitrary 32-bit value that represents a group of PWs that is
      used to create groups in the PW space.  The Group ID is intended
      to be used as a port index or a virtual tunnel index.  To simplify

      egress router.  The Group ID is very useful for sending wildcard
      label withdrawals or PW wildcard status Notification messages to
      remote PEs upon physical port failure or transport tunnel failure.



Notes
-----
The PW group can be created on basis of the transport tunnel index.

So  Group Id can be used to send PW wildcard status notification to remote PEs on physical port failure or Transport tunnel failure.
