A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Layer 3 Virtual Private Networks Working Group of the IETF. Title : Architecture for the Use of PE-PE IPsec Tunnels in BGP/MPLS IP VPNs Author(s) : E. Rosen, et al. Filename : draft-ietf-l3vpn-ipsec-2547-05.txt Pages : 18 Date : 2005-8-8 In BGP/MPLS IP Virtual Private Networks (VPNs), VPN data packets traveling from one Provider Edge (PE) router to another generally carry two MPLS labels, an "inner" label that corresponds to a VPN- specific route, and an "outer" label that corresponds to a Label Switched Path (LSP) between the PE routers. In some circumstances, it is desirable to support the same type of VPN architecture, but using an IPsec Security Association in place of that LSP. The "outer" MPLS label would thus be replaced by an IP/IPsec header. This enables the VPN packets to be carried securely over non-MPLS networks, using standard IPsec authentication and/or encryption functions to protect them. This draft specifies the procedures which are specific to support of BGP/MPLS IP VPNs using the IPsec encapsulation.

You can also visit https://www1.ietf.org/mailman/listinfo/I-D-announce to change your subscription settings. Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-ietf-l3vpn-ipsec-2547-05.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-l3vpn-ipsec-2547-05.txt". 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.
