MLAG Spine - All Active Multipath for Layer 2

  • Standards based protocol (LACP)
  • Simplified or eliminates Spanning Tree topology
  • Simple to understand and easy to engineer traffic

ECMP - All Active Multipath for Layer 3

  • Standards based protocol (OSPF, BGP)
  • Eliminates L2 for exceptional scalability and fault tolerance
  • Exceptional scale with consistent performance in 2 tiers

VXLAN Layer 2 over Layer 3 - Best of Both Worlds

  • All active multipath using ECMP (up to 64-way)
  • Single L3 network for all applications
  • L2 extensions for stateful VM - VM over Layer 3
  • Extends L2 with exceptional scalibilty (16M Virtual NWs)
  • Cloudburst over public infrastructure
