      vrfs:
        - name: Production
          vrf_id: 50001
          vlan_id: 2901
          vrf_attach_group: all_sites
      vrf_attach_groups:
        - name: all_sites
          switches:
            - hostname: A-BGW_SuperSpine1
            - hostname: A-BGW_SuperSpine2
            - hostname: B-BGW_SuperSpine1
