Layer 3 integration using a VLAN

  • In limited use cases, there may be a requirement for VLAN to be configured to enable routing services with the upstream network. In this event, the same rules apply for preparing for Layer 3 integration using either static routing or BGP, but the exception is that a VLAN is assigned for the transport between the two network layers.

    Figure 23.          Layer 3 integration using a VLAN

    To prepare for Layer 3 integration using a VLAN, perform the following tasks:

    • Identify the VLAN to be used for transport services between the two network layers.
    • Configure the upstream network for routing services between the two network layers. Configure static routes if static routing will be used, or configure BGP if BGP peering will be used.
    • Configure the VLAN to be used for Layer 3 transport services on the upstream network.
    • Identify the network to be routed using VLAN-enabled routing services.

    The ‘VLAN – Layer 3 Settings’ table in Appendix A: VxRail with SmartFabric network configuration tables can be used to capture the setting to enable routing services with the upstream network using a VLAN.
