  2. Changes from Last Version • Terminology updated to align with EVPN draft • Term MES deprecated • Revised NLRI to more efficiently encode B-MACI-SID relationships

  3. Revised NLRI +---------------------------------------+ | RD (8 octets) | +---------------------------------------+ |Ethernet Segment Identifier (10 octets)| +---------------------------------------+ | B-MAC Address Length (1 octet) | +---------------------------------------+ | B-MAC Address (6 octets) | +---------------------------------------+ | MPLS Label (n * 3 octets) | +---------------------------------------+ | Base I-SID (3 octets) | +---------------------------------------+ | I-SID vector length (1 octet) | +---------------------------------------+ | I-SID vector (var length) | // // +---------------------------------------+ As per base draft • I-SID vector encodes contiguous I-SID list, each I-SID represented by 3 bits • 1=Y, 0=N +--+--+--+ | R| T| I| +--+--+--+ 2 1 0 M’cast Receive interest M’cast Xmit interest I-SID interest

  4. Next Steps • Seek to align revised NLRI with PBB-EVPN draft • I-SID pinning would benefit from compressed encoding • Address multicast stitching • Fill in 802.1Qbp details • F-tag manipulation • Mapping of multicast (will be different from 802.1aq) • Comments from the list • WG adoption
