Abstract:
   OSPF is one of the used underlay routing protocol for MSDC (Massively
   Scalable Data Center) networks.  For a given OSPF router within the
   CLOS topology, it would receive multiple copies of exactly the same
   LSA from multiple OSPF neighbors.  In addition, two OSPF neighbors
   may send each other the same LSA simultaneously.  The unnecessary
   link-state information flooding wastes the precious process resource
   of OSPF routers greatly due to the presence of too many OSPF
   neighbors for each OSPF router within the CLOS topology.  This
   document proposes extensions to OSPF so as to reduce the OSPF
   flooding within such MSDC networks.  The reduction of the OSPF
   flooding is much beneficial to improve the scalability of MSDC
   networks.  These modifications are applicable to both OSPFv2 and
   OSPFv3.
