The IESG has received a request from the Layer 3 Virtual Private Networks WG (l3vpn) to consider the following document: - 'Virtual Hub-and-Spoke in BGP/MPLS VPNs' <draft-ietf-l3vpn-virtual-hub-06.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-06-06. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract With BGP/MPLS VPNs, providing any-to-any connectivity among sites of a given Virtual Private Network would require each Provider Edge router that has one or more of these sites connected to it to hold all the routes of that Virtual Private Network. The approach described in this document allows to reduce the number of Provider Edge routers that have to maintain all these routes by requiring only a subset of these routers to maintain all these routes. Furthermore, when Provider Edge routers use ingress replication to carry multicast traffic of VPN customers, the approach described in this document may under certain circumstances allow to reduce bandwidth inefficiency associated with ingress replication, and to redistribute the replication load among Provider Edge routers. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-l3vpn-virtual-hub/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-l3vpn-virtual-hub/ballot/ No IPR declarations have been submitted directly on this I-D.
