[mpls] clarification on RFC 4447: Pseudowire Setup and Maintenance Using the Label Dist

[Dinesh <dineshbs123 at gmail.com>]

Hi,

This RFC does not address the case were one end point of attachment circuit is a qinq vlan and remote
attachment end point is a dot1q single tag vlan. Currently ether type vlan is used and this does not help the
PEs to  do proper insert/modify of the pw data  as they do not actually know if the received packet has single tag or double tag.

I want the PE to send out L2 frame with dot1p bits so that i can provide COS at remote end.
 if we use  vc-type ether, the  vlan information is not sent on the wire. and if vlan info is sent using vc-type  vlan, then
there is confusion if received data is a single tagged or double tagged. Please  clarify this.

Regards
dinesh
