  2. Updates from version 5 • Terminology Updates • General • VPLS instance = VPLS Domain • VPLS Site = CE site (Single-homed or Multihomed) • NLRI • VE NLRI • Non-zero VE Block Offset, Size and Label base) • Unique per VPLS Instance • CE NLRI (MH NLRI) • Zero based VE Block Offset, Size and Label base) • Unique per CE site (Mhed)

  3. Updates from version 5 • Provisioning Model • Simultaneous assignment of both VE and CE IDs per VPLS instance • Ext. Community bits clarified extensively • D-bit • VE NLRI (Instance) • CE NLRI (All AC links) • F-bit • VE NLRI (Instance)

  4. Updates from version 5 • MAC Flush Redefined • Previous • Explicit flush via MAC list for subset of MAC addresses belonging to a single PE • Inference to old Kothari’s MAC flush draft for BGP and to RFC 4762 for LDP • Implicit flush via BGP Route Withdrawal OR D/F bit signals (On/Off respectively) • Now • Removed “explicit flush” and left “implicit flush” as only requirement

  5. WG Request • Soliciting feedback on previous (ver.4 & ver.5) on RD changes and on backward compatibility section from folks who have had already deployed multi-homing with VPLS non-zero NLRI • Section 6.1 in specific • Soliciting feedback on ver 6 updates • No Request for the last call in Berlin; pending feedback
