Hi authors,
If the PE provides active&standby packet PW, then will the two PW be
configured with same unicast Ethernet addresses (PacketPWEthA and
PacketPWEthB), or different? If different, what kind of unicast Ethernet
addresses could be used?

And, I think section 1&4 needs to be revised since virtual ethernet approach
is selected, see below.
Section 1, Introduction
   Where the client LSR and server PE is co-located in the same
   equipment, the data-link layer can be simplified to a simple protocol
   identifier (PID) that is used to multiplex the various data-link
   types onto a pseudowire.
[Lizhong] the PID concept is for PID label approach, not virtual ethernet
approach.

 Section 4, Forwarding Model
This LSR determines the next hop in the client
   layer, and pushes the label needed by the next hop in the client
   layer.  It then passes the packet to the correct PW instance
   indicating the packet protocol type.  If the PW is configured to
   require a CW this is pushed.  The PW instance then examines the
   protocol type and pushes a label that identifies the protocol type...
[Lizhong] The procedure defined above seems to be the PID label approach,
not virtual ethernet approach.

Regards
Lizhong
