Network Design Models#

Please review the core concepts first to learn more about VergeOS Network types before reviewing this document.

The following network models are designed for redundancy

Generic Requirements (All network design models)#

  • For environments with more than 2 nodes, switches are required for Core Fabric Networks

  • Jumbo Frames configured on all Core Fabric Network switchports

    • Minimum MTU size 9000
    • Recommended MTU size of 9192 and above

  • Core Fabric Networks 1 and 2 on their own dedicated layer 2 networks

  • VergeOS Systems located in the same site need to be completely isolated from eachother

Layer 2 Static + Dedicated Core Fabric#

This model uses a bonded Layer 2 network for the External, UI and API Management Networks, while maintaining dedicated Layer 2 networks for the Core Fabric traffic.

Use Cases#

  • High performance production environments
  • Existing VMware environments using a Distributed Switch
  • Environments where you want to deploy VMs directly in VLANs that are External to VergeOS

Requirements#

  • 4 x 10/25/40/100GbE NICs
  • Switching infrastructure that supports stacking (MLAG) - For External Network

Network Configuration#

  • 4 VergeOS Physical Networks:

    • Core Fabric Network 1
    • Core Fabric Network 2
    • External Network 1 - Primary bond
    • External Network 2 - Secondary bond

  • Core Fabric Networks 1 and 2 on their own dedicated layer 2 networks

  • A single VLAN for UI/API Management (on primary bonded External Network)
  • Any other VLANs required for your workloads (on primary bonded External Network)

Layer 2 Bonded + Dedicated Core

Layer 3 Dynamic + Dedicated Core Fabric#

This model uses dynamically advertised Layer 3 networks for the External, UI and API Management Networks, while maintaining dedicated Layer 2 networks for the Core Fabric traffic.

Use Cases for L3+DC#

  • High performance production environments
  • Large-scale deployments
  • Environments requiring advanced network segmentation

Requirements#

  • 4 x 10/25/40/100Gb network adapters
  • A layer 3 network External to the System that VergeOS can peer with
  • BGP, OSPF, or EIGRP capabilities
  • Using VergeOS Internal Networks for workloads

Network Configuration#

  • 4 VergeOS Physical Networks:

    • Core Fabric Network 1
    • Core Fabric Network 2
    • External Network 1
    • External Network 2

  • Core Fabric Networks 1 and 2 on their own dedicated layer 2 networks

  • A single dynamically advertised network for UI/API Management
  • Any other dynamically advertised networks required for your workloads

Layer 3 Bonded + Dedicated Core

Layer 3 Static + Dedicated Core Fabric#

This model uses a bonded Layer 3 network for the External, UI and API Management Networks, while maintaining dedicated Layer 2 networks for the Core Fabric traffic.

Use Cases for L3+DC#

  • High performance production environments
  • Large-scale deployments
  • Environments requiring advanced network segmentation

Requirements#

  • 4 x 10/25/40/100Gb network adapters
  • Switching infrastructure that supports stacking (MLAG) - For External Network
  • Layer 3 capable switching infrastructure for the External network
  • Using VergeOS Internal Networks for workloads

Network Configuration#

  • 4 VergeOS Physical Networks:

    • Core Fabric Network 1
    • Core Fabric Network 2
    • External Network 1 - Primary bond
    • External Network 2 - Secondary bond

  • Core Fabric Networks 1 and 2 on their own dedicated layer 2 networks

  • A single statically routed network for UI/API Management
  • Any other statically routed networks required for your workloads

Layer 3 Bonded + Dedicated Core

Layer 2 Static using 2 NICs#

In this model, all networks (Core Fabric, External/Management, Workloads) are combined into a single bonded network VergeOS Physical Network.

Use Cases - 2 NICs#

  • Proof of concepts
  • Small Edge deployments
  • Disaster recovery setups
  • Development workloads
  • Bare Metal Cloud Providers

Each statically assigned network you route to VergeOS in this system design will be non-redunant

Requirements - 2 NICs#

  • 2 x 10/25/40/100GbE network adapters
  • Ability to trunk VLANs and set a native VLAN on switch

Network Configuration - 2 NICs#

  • 2 Physical Networks

    • Core Fabric Network 1
    • Core Fabric Network 2

  • All networks VLAN tagged

  • Core Network VLANs set as native
  • A single VLAN for UI/API Management (Either Core Fabric Network)
  • Any other VLANs required for your workloads (Either Core Fabric Network)

Layer 2 Bonded

By choosing the appropriate network design model based on your specific use case and requirements, you can ensure optimal performance and scalability for your VergeOS deployment.
