Managing route domains

Route Domains provide a way to define and manage EVPN-based Layer 3 routing isolation boundaries across your network fabric.

A route domain is a container that represents a VRF and its related settings, such as the L3VNI and L3VLAN, needed for EVPN-based VRFs.

Creating a route domain

Section titled “Creating a route domain”

To create a new Route Domain, follow the multi-step process below:

  1. Initiate Creation: Go to the Fabric Manager, select Route Domain from the left menu, and click Add Route Domain.
  2. Basic Information: Provide the following details:
    • Name & Label: Give the route domain a unique name and identifying label.
    • Kind: Select the type of domain (currently, only EVPN L3VPN is supported).
    • Preconfigured VRF: Select if the VRF already exists on the network devices.
      • Note: If set to true, MetalSoft does not manage the VRF; it must be pre-created, and MetalSoft does not modify or remove it.
    • Auto Route Distinguisher: Enable this if you want the switch to auto-generate the EVPN Route Distinguisher for the L3 VNI (only applicable to EVPN L3VPN).
    • Auto Route Target: Enable this if you want the switch to auto-generate EVPN Route Targets for the L3 VNI (only applicable to EVPN L3VPN).
  3. VRF Allocation: Click Next to proceed to the VRF Allocation page:
    • Strategy: Select how the VRF will be allocated (currently, Manual is the only option).
    • Network Device Driver: Select the driver type (this determines the naming requirements for the VRF).
    • VRF Name: Enter the name for the VRF.
    • Scope: Select the scope (currently, Global is supported).
  4. L3 VLAN Allocation: Click Next to proceed to the L3 VLAN Allocation page:
    • Enable L3 VLAN Allocation: Toggle this setting on or off.
    • If enabled, configure the following:
      • Strategy: Select Auto or Manual. If Manual is selected, enter the specific VLAN ID.
      • Scope: Select the scope (currently, Global is supported).
      • Granularity Level: Select the granularity (currently, Fabric is supported).
  5. L3 VNI Allocation: Click Next to proceed to the L3 VNI Allocation page:
    • Strategy: Select Auto or Manual. If Manual is selected, enter the specific VNI to use.
    • Scope: Select the scope (currently, Global is supported).
    • Granularity Level: Select the granularity (currently, Fabric is supported).
  6. Finalize: Click Add to complete and save the Route Domain.

Assigning a route domain

Section titled “Assigning a route domain”

Once you create a Route Domain, you can assign it to your network components to begin routing.

To assign a Route Domain, create one of the following entities and select the appropriate Route Domain on the Overview page:
