Here a sample of command with pvesh to manage the sdn.


#create a vlan transportzone
pvesh create /cluster/sdn/zones/ --zone vlanzone --type vlan --bridge vmbr0


#create a layer2 vxlan unicast transportzone
pvesh create /cluster/sdn/zones/ --zone vxlanunicastzone --type vxlan --peers 192.168.0.1,192.168.0.2,192.168.0.3

#create an controller
pvesh create /cluster/sdn/controllers/ --controller frrrouter1 --type evpn --peers 192.168.0.1,192.168.0.2,192.168.0.3 --asn 1234 --gateway-nodes pxnode1,pxnode2 --gateway-external-peers 192.168.0.253,192.168.0.254

#create a layer2 vxlan bgpevpn transportzone
pvesh create /cluster/sdn/zones/ --zone layer2evpnzone --type evpn --controller frrrouter1

#create a layer3 routable vxlan bgpevpn transportzone
pvesh create /cluster/sdn/zones/ --zone layer3evpnzone --type evpn --controller frrrouter1 --vrf-vxlan 4000


#create a vnet in the transportzone
pvesh create /cluster/sdn/vnets/ --vnet vnet10 --type vnet --zone vlanzone --tag 10

#create a vnet in the transportzone with ip for evpn routing
pvesh create /cluster/sdn/vnets/ --vnet vnet11 --type vnet --zone layer3evpnzone --tag 11 --ipv4 10.0.0.1/24 --mac c8:1f:66:f8:62:8d
pvesh create /cluster/sdn/vnets/ --vnet vnet12 --type vnet --zone layer3evpnzone --tag 12 --ipv4 10.0.1.1/24 --mac c8:1f:66:f8:62:8e


#apply changes from /etc/pve/sdn.cfg.new to /etc/pve/sdn.cfg
pvesh set /cluster/sdn


#generate local /etc/network/interfaces.d/sdn  and reload  (need to be called on each node)
 pvesh set /nodes/<node>/network


display transporzone status on all cluster nodes
#pvesh get /cluster/resources
