• LDP FEC Node Group
• New draft
• Purpose is to provide a method that can be used
  to
• guide traffic via preferred nodes when equal
  cost
• path is available for P2P LDP LSPs.
• To setup node disjoint P2MP mLDP LSPs
• Each node can advertise its groups to neighbors
• Each label map msg can carry groups for each FEC
• with loose strict option
• Node while sending label map may propagate
• label map only towards an upstream node if node
• group and FEC group matches
• Applicable to P2P P2MP/MP2MP LDP LSP signaling
• It is optional and no changes to basic LDP
  signaling
• Requesting comments on mailing list
