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


#create a vlan transportzone
pvesh create /cluster/sdn/zones/ --zone vlanzone --type vlan --ipam pve --bridge vmbr0
#create a vnet on vlanzone
pvesh create /cluster/sdn/vnets/ --vnet vnet100 --type vnet --zone vlanzone --tag 100
#create a subnet on vlanzone
pvesh create /cluster/sdn/vnets/vnet100/subnets/ --type subnet --subnet 192.168.0.0/24 --gateway 192.168.0.1


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

#create an evpn controller
pvesh create /cluster/sdn/controllers/ --controller evpn1 --type evpn --peers 192.168.0.1,192.168.0.2,192.168.0.3 --asn 1234

#add a ebgp peer
pvesh create /cluster/sdn/controllers/ --controller bgp1 --type bgp --peers 192.168.0.253,192.168.0.254 --asn 1234 --ebgp --node pxnode1

#create a layer2 vxlan bgpevpn transportzone
pvesh create /cluster/sdn/zones/ --zone layer2evpnzone --type evpn --ipam pve --controller evpn1

#create a layer3 routable vxlan bgpevpn transportzone + exit-nodes
pvesh create /cluster/sdn/zones/ --zone layer3evpnzone --type evpn --ipam pve --controller evpn1 --vrf-vxlan 4000 --exit-nodes pxnode1,pxnode2



#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 subnets for evpn routing
pvesh create /cluster/sdn/vnets/ --vnet vnet11 --type vnet --zone layer3evpnzone --tag 11 --mac c8:1f:66:f8:62:8d
pvesh create /cluster/sdn/vnets/vnet11/subnets/ --type subnet --subnet 10.0.0.0/24 --gateway 10.0.0.1
pvesh create /cluster/sdn/vnets/ --vnet vnet12 --type vnet --zone layer3evpnzone --tag 12 --mac c8:1f:66:f8:62:8e
pvesh create /cluster/sdn/vnets/vnet11/subnets/ --type subnet --subnet 10.0.1.0/24 --gateway 10.0.1.1

#display running configuration
pvesh get /cluster/sdn/vnets --running
pvesh get /cluster/sdn/zones --running
pvesh get /cluster/sdn/controllers --running
pvesh get /cluster/sdn/vnets/vnetX/subnets --running


#display pending configuration
pvesh get /cluster/sdn/vnets --pending
pvesh get /cluster/sdn/zones --pending
pvesh get /cluster/sdn/controllers --pending
pvesh get /cluster/sdn/vnets/vnetX/subnets --pending


#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
