tenant_network_types = vlan 
type_drivers = vlan 
mechanism_drivers = openvswitch, extreme_efa 
[ml2_type_vlan] 
network_vlan_ranges = physnet1:2:500 
[ovs] 
bridge_mappings = physnet1:br1

Configure efa_rest_token, region_name, and region_shared in /etc/neutron/plugins/ml2/ml2_conf_extreme.ini.

[ml2_extreme]
efa_rest_token = <efa_api_token for VIM_1>
efa_cert_file = /root/gcla/extreme-ca-chain.crt
efa_secure_mode = True
efa_port = 443
efa_host = efa.extremenetworks.com
region_name = VIM_1
region_shared = SHARED_TENANT
#SHARED_TENANT is the name of the shared tenant created on EFA
fabric_name = CNCF
[efa_topology]
efa_link_mapping_file = /home/ubuntu/link.csv
