Examples

L2 Handoff with Anycast Gateway:

catalyst_center:
  fabric:
    border_devices:
      - name: BR01
        border_types:
          - LAYER_3
          - LAYER_2
        default_exit: true
        import_external_routes: false
        local_autonomous_system_number: 65001
        external_domain_routing_protocol_name: BGP
        l2_handoffs:
          l2_with_anycast_gateway:
            - name: Campus
              external_vlan: 400
              interfaces:
                - GigabitEthernet1/0/8
                - GigabitEthernet1/0/9

To create L2 handoff with anycast gateway, name has to match L3 virtual network name configured under l3_virtual_networks:

---
catalyst_center:
  fabric:
    fabric_sites:
      - name: Global/Poland/Krakow
        authentication_template_name: No Authentication
        pub_sub_enabled: true
        l3_virtual_networks:
          - name: Campus

L2 Handoff without Anycast Gateway:

catalyst_center:
  fabric:
    border_devices:
      - name: BR01
        border_types:
          - LAYER_3
          - LAYER_2
        default_exit: true
        import_external_routes: false
        local_autonomous_system_number: 65001
        external_domain_routing_protocol_name: BGP
        l2_handoffs:
          l2_without_anycast_gateway:
            vlans:
              - name: L2_VLAN_USERS
                external_vlan: 500
            interfaces:
              - GigabitEthernet1/0/6
              - GigabitEthernet1/0/7

To create L2 handoff without anycast gateway, name of vlan have to match vlan name created under l2_virtual_networks:

---
catalyst_center:
  fabric:
    fabric_sites:
      - name: Global/Poland/Krakow
        authentication_template_name: No Authentication
        pub_sub_enabled: true
        l2_virtual_networks:
          - name: L2_SDA_VN_1
            vlan_name: L2_VLAN_USERS
            vlan_id: 501
            traffic_type: DATA
            fabric_enabled_wireless: false
