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:
