	Title		: VPLS Interoperability with CE Bridges

One of the main motivations behind VPLS is its ability to provide 
   connectivity not only among customer routers and servers/hosts but 
   also among customer bridges. If only connectivity among customer IP 
   routers/hosts was desired, then IPLS solution [IPLS] could have been 
   used. The strength of the VPLS solution is that it can provide 
   connectivity to both bridge and non-bridge types of CE devices. VPLS 
   is expected to deliver the same level of service that current 
   enterprise users are accustomed to from their own enterprise bridged 
   networks today or the same level of service that they receive from 
   their Ethernet Service Providers using IEEE 802.1ad-based networks 
   [P802.1ad] (or its predecessor – QinQ-based network). 
    
   When CE devices are IEEE bridges, then there are certain issues and 
   challenges that need to be accounted for in a VPLS network. Majority 
   of these issues have currently been addressed in IEEE 802.1ad 
   standard for provider bridges and they need to be addressed for VPLS 
   networks. This draft discusses these issues and wherever possible, 
   the recommended solutions to these issues.

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.
