Introduction

  • The VCF on VxRail network design offers flexibility to allow for different topologies and different network hardware vendors. This flexibility enables you to use your existing network infrastructure or potentially add new hardware to an existing data center network infrastructure. Typically, data center network design has been shifting away from classical 3-tier network topologies using primarily Layer 2 fabric to the newer Leaf and Spine Layer 3 fabric architectures. When deciding whether to use Layer 2 or Layer 3, consider:

    • The investment that you have today in your current physical network infrastructure
    • The advantages and disadvantages for both Layer 2 and Layer 3 designs

    NSX-T ECMP Edge devices establish Layer 3 routing adjacency with the first upstream Layer 3 device to provide equal cost routing for management and workload traffic.

    The following section describes both designs and highlights the main advantages and disadvantages of each design.
