Managing Route Domains

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

The route domain is a container that represents a VRF, and it’s related settings like the L3VNI and L3VLAN, which are needed for EVPN based VRFs

Creating a Route Domain

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

Initiate Creation: Go to the Fabric Manager, select Route Domain from the left menu, and click Add Route Domain.
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, the VRF will not be managed by Metalsoft; it must be pre-created and Metalsoft will 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).
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).
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).
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).
Finalize: Click Add to complete and save the Route Domain.

Assigning a Route Domain

Once a Route Domain is created, 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:
