  1. PIM DR Load Balancing Yiqun Cai, Heidi Ou, Sri Valepalli, Andy Green draft-ietf-pim-drlb-02 IETF 86, Orlando

  2. Status • draft-hou-pim-drlbpresented at IETF 82, Taipei, accepted as WG draft-ietf-pim-drlb-00 • draft-ietf-pim-drlb-01 presented at IETF 83, Paris draft-hou-pim-drlb-02

  3. Overview • Elect multiple forwarders on the last hop LAN • Each is called a GDR (Group DR) • Hashing is used to determine which candidate GDR becomes the GDR • Forwarding load is now distributed • During a failover only a subset of the forwarding states need to be rebuilt draft-hou-pim-drlb-02

  4. Update From draft-ietf-pim-drlb-01 • GDR Election Hash Algorithm • Changed to BSR style hash algorithm • Hello Options • Remove Load Balance Mask (LBM) option • Move Group/Source/RP Masks into LBGDR option, advertised by DR only • A new Load Balance Capability option (LBC) draft-hou-pim-drlb-02

  5. After That… • More experiment on GDR hash algorithm • Implementation draft-hou-pim-drlb-02
