Status as of IETF-65

• Two approaches had been under active
  consideration
• MANET Designated Routers (MDR) originally
  proposed by R. Ogier
• Flooding via CDS, adjacency pruning, advertised
  topology reduction, and other optimizations
• Overlapping Relays and Smart Peering (OR/SP) by
  Cisco team
• Flooding via MPRs and backups (ORs), adjacency
  pruning via SP, and other optimizations

Status as of IETF-65 (cont.)

• A third approach published in February
• OSPF MPR Extension for Ad Hoc Networks by INRIA
  team
• Flooding via MPRs, adjacencies only between MPRs
  and MPR Selectors, special Synch nodes to
  guarantee connectivity, multicast LSA acks
• Meeting outcomes
• Proposal by subset of design team to move forward
  with an MDR-based solution caused vigorous
  discussion
• INRIA agreed to produce further technical results
  for consideration
