  1. BGP L2VPNAuto-discovery and Signaling Kireeti Kompella

  2. Old, Old Document • Pre-dates BGP VPLS • Introduces an NLRI for L2VPNs • L2VPN is defined as a set of PWs that connect sites of a single enterprise (as opposed to a single PW)

  3. Re-uses 4364 Concepts • Route Distinguisher to make “routes” unique • Route Target to determine VPN topology

  4. What’s New in BGP? • New NLRI • contains RD and “site ID” • also contains a label block • Well, not really new: it is the same NLRI used in BGP VPLS: same format and AFI/SAFI • Only difference: “circuit vector status” TLV

  5. Other Extensions • Extended community “L2 info” that carries PW encap and other information • Again, same as in BGP VPLS, but with new encap types (the usual: ATM, FR, PPP, Ethernet, …, and of course, VPLS)

  6. Changes to Document • Since it predated BGP VPLS, this doc had all BGP format and processing information • BGP VPLS referred to this one • Situation now reversed • Almost all BGP info in BGP VPLS RFC • Almost all removed from this one • If you notice any more that should be nuked, being redundant, please let me know

  7. So, Where Are We? • We now have a doc that says how to use the BGP extensions for auto-discovery and signaling defined in RFC 4761 to build a (P2P) L2VPN • minor changes in processing • new encap types • new data plane procedures

  8. Next Steps • “Liaise” this to the IDR (no serious changes, but let them decide) • Change the author from “kompella” to “ietf” • I.e., make it an L2VPN WG doc • Publish it :-)
