Technical Summary
The PWE3 encapsulation specifications for Ethernet, Frame Relay,
and HDLC pseudowires Ethernet, Frame Relay, and HDLC pseudowires
require that the original Frame Check Sequence (FCS) be removed
at pseudowire ingress and regenerated at pseudowire egress.
This document defines an optinal mechanism for preserving frame
FCS and transporting it over the pseudowire.
Working Group Summary
The PWE3 WG have thoroughly reviewed this design. There are mixed
opinions in the PWE3 WG on how beneficial this option is.
Protocol Quality
This is a simple modification to a well known encapsulation
and the associated signalling protocol. The document was
reviewed by Mark Townsley.
