Multi-segment pseudowires have been defined to enable emulated layer 
   1 and layer 2 services to be delivered from an IP based packet 
   switched network over a sparse mesh of PSN tunnels and PW control 
   protocol sessions. MS-PWs can be used to scale PW based networks over 
   both a single AS, or between multiple ASs, and there is a particular 
   need to be able to dynamically route MS-PWs through a given AS to 
   reach PEs at or beyond the edge of the AS, where the route of the PW 
   through each AS needs to be automatically determined. 

   This draft proposes extensions to OSPF to enable the automatic 
   advertisement of summarized PW FECs, thus enabling the dynamic 
   routing of MS-PWs across an OSPF domain.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
