	Title		: Use of Multiple Instance of OSPF for the PE/CE 
                          protocol in BGP/MPLS VPNs

This document describes a simple way to use OSPF for Provider Edge
(PE) router and Customer Edge (CE) router communication in BGP/MPLS
VPNs [RFC2547BIS].  [VPN-BGP-OSPF] proposes a complicated way to
achieve VPN route propagation as Type-3 LSAs.  This document
describes the use of multiple instances of OSPF in conjunction with
standard BGP/OSPF route redistribution mechanisms to maintain
reachability information throughout VPNs.  With this mechanism, VPN
routes are propagated as Type-5 LSAs.

In the body type:

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.
