17 | Installation |
18 | ------------ | |
19 | ||
684db7e3 TL |
20 | To enable the experimental SDN integration, you need to install the |
21 | `libpve-network-perl` and `ifupdown2` package on every node: | |
1556b768 AD |
22 | |
23 | ---- | |
684db7e3 TL |
24 | apt update |
25 | apt install libpve-network-perl ifupdown2 | |
1556b768 AD |
26 | ---- |
27 | ||
684db7e3 | 28 | After that you need to add the following line: |
1556b768 | 29 | |
a6af82c7 AD |
30 | ---- |
31 | source /etc/network/interfaces.d/* | |
32 | ---- | |
684db7e3 TL |
33 | at the end of the `/etc/network/interfaces` configuration file, so that the SDN |
34 | config gets included and activated. | |

37 | Basic Overview |
38 | -------------- | |
39 | ||
40 | The {pve} SDN allows separation and fine grained control of Virtual Guests | |
41 | networks, using flexible software controlled configurations. | |
42 | ||
8ac25ffe TL |
43 | Separation consists of zones, a zone is it's own virtual separated network area. |
44 | A 'VNet' is a type of a virtual network connected to a zone. Depending on which | |
45 | type or plugin the zone uses it can behave differently and offer different | |
46 | features, advantages or disadvantages. | |
47 | Normally a 'VNet' shows up as a common Linux bridge with either a VLAN or | |
48 | 'VXLAN' tag, but some can also use layer 3 routing for control. | |
49 | The 'VNets' are deployed locally on each node, after configuration was committed | |
60ed554f | 50 | from the cluster-wide datacenter SDN administration interface. |
ee6e18c4 TL |
51 | |
52 | ||
1556b768 | 53 | Main configuration |
a6af82c7 | 54 | ~~~~~~~~~~~~~~~~~~ |
1556b768 | 55 | |
ee6e18c4 TL |
56 | The configuration is done at datacenter (cluster-wide) level, it will be saved |
57 | in configuration files located in the shared configuration file system: | |
58 | `/etc/pve/sdn` | |
1556b768 | 59 | |
a6af82c7 | 60 | On the web-interface SDN feature have 3 main sections for the configuration |
1556b768 | 61 | |
ee6e18c4 | 62 | * SDN: a overview of the SDN state |
1556b768 | 63 | |
ee6e18c4 | 64 | * Zones: Create and manage the virtual separated network Zones |
1556b768 | 65 | |
a6af82c7 AD |
66 | * VNets: Create virtual network bridges + subnets management. |
67 | ||
68 | And some options: | |
1556b768 | 69 | |
8ac25ffe | 70 | * Controller: For complex setups to control Layer 3 routing |
1556b768 | 71 | |
3093e62d | 72 | * Sub-nets: Used to defined ip networks on VNets. |
a6af82c7 | 73 | |
3093e62d | 74 | * IPAM: Allow to use external tools for IP address management (guest IPs) |
a6af82c7 | 75 | |
3093e62d TL |
76 | * DNS: Allow to define a DNS server api for registering a virtual guests |
77 | hostname and IP-addresses | |

81 | SDN |
82 | ~~~ | |
83 | ||
ee6e18c4 TL |
84 | This is the main status panel. Here you can see deployment status of zones on |
85 | different nodes. | |
1556b768 | 86 | |
ee6e18c4 | 87 | There is an 'Apply' button, to push and reload local configuration on all |
60ed554f | 88 | cluster nodes. |

92 | Local Deployment Monitoring | |
93 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
94 | ||
95 | After applying the configuration through the main SDN web-interface panel, | |
96 | the local network configuration is generated locally on each node in | |
97 | `/etc/network/interfaces.d/sdn`, and with ifupdown2 reloaded. | |
98 | ||
99 | You can monitor the status of local zones and vnets through the main tree. | |
100 | ||

4e652aba | 102 | [[pvesdn_config_zone]] |
1556b768 | 103 | Zones |
a6af82c7 | 104 | ----- |
1556b768 | 105 | |
ee6e18c4 | 106 | A zone will define a virtually separated network. |
1556b768 | 107 | |
ee6e18c4 | 108 | It can use different technologies for separation: |
1556b768 | 109 | |
ee6e18c4 | 110 | * VLAN: Virtual LANs are the classic method to sub-divide a LAN |
1556b768 | 111 | |
ee6e18c4 | 112 | * QinQ: stacked VLAN (formally known as `IEEE 802.1ad`) |
1556b768 | 113 | |
ee6e18c4 | 114 | * VXLAN: (layer2 vxlan) |
1556b768 | 115 | |
a6af82c7 AD |
116 | * Simple: Isolated Bridge, simple l3 routing bridge (NAT) |
117 | ||
ee6e18c4 | 118 | * bgp-evpn: vxlan using layer3 border gateway protocol routing |
1556b768 AD |
119 | |
120 | You can restrict a zone to specific nodes. | |
121 | ||
ee6e18c4 TL |
122 | It's also possible to add permissions on a zone, to restrict user to use only a |
123 | specific zone and only the VNets in that zone | |
1556b768 | 124 | |
a6af82c7 AD |
125 | Common options |
126 | ~~~~~~~~~~~~~~ | |
1556b768 | 127 | |
3093e62d TL |
128 | The following options are available for all zone types. |
129 | ||
a6af82c7 AD |
130 | nodes:: Deploy and allow to use a VNets configured for this Zone only on these |
131 | nodes. | |
9e773815 | 132 | |
3093e62d | 133 | ipam:: Optional, if you want to use an ipam tool to manage ips in this zone |
1556b768 | 134 | |
3093e62d | 135 | dns:: Optional, dns api server. |
1556b768 | 136 | |
3093e62d | 137 | reversedns:: Optional, reverse dns api server. |
1556b768 | 138 | |
3093e62d TL |
139 | dnszone:: Optional, dns domain name. Use to register hostname like |
140 | `<hostname>.<domain>`. The dns zone need to be already existing in dns server. | |

143 | [[pvesdn_zone_plugin_simple]] |
144 | Simple Zones | |
145 | ~~~~~~~~~~~~ | |
1556b768 | 146 | |
a6af82c7 AD |
147 | This is the simplest plugin, it will create an isolated vnet bridge. |
148 | This bridge is not linked to physical interfaces, VM traffic is only | |
149 | local to the node(s). | |
150 | It can be also used for NAT or routed setup. | |
1556b768 | 151 | |
4e652aba | 152 | [[pvesdn_zone_plugin_vlan]] |
ee6e18c4 TL |
153 | VLAN Zones |
154 | ~~~~~~~~~~ | |
1556b768 | 155 | |
a6af82c7 AD |
156 | This plugin will reuse an existing local Linux or OVS bridge, |
157 | and manage VLANs on it. | |
ee6e18c4 TL |
158 | The benefit of using SDN module, is that you can create different zones with |
159 | specific VNets VLAN tag, and restrict Virtual Machines to separated zones. | |
1556b768 | 160 | |
ee6e18c4 | 161 | Specific `VLAN` configuration options: |
1556b768 | 162 | |
a91b3e7f | 163 | bridge:: Reuse this local bridge or OVS switch, already |
ee6e18c4 | 164 | configured on *each* local node. |
1556b768 | 165 | |
4e652aba | 166 | [[pvesdn_zone_plugin_qinq]] |
ee6e18c4 TL |
167 | QinQ Zones |
168 | ~~~~~~~~~~ | |
1556b768 | 169 | |
ee6e18c4 TL |
170 | QinQ is stacked VLAN. The first VLAN tag defined for the zone |
171 | (so called 'service-vlan'), and the second VLAN tag defined for the vnets | |
1556b768 | 172 | |
8ac25ffe | 173 | NOTE: Your physical network switches must support stacked VLANs! |
1556b768 | 174 | |
ee6e18c4 | 175 | Specific QinQ configuration options: |
1556b768 | 176 | |
4e652aba TL |
177 | bridge:: A local VLAN-aware bridge already configured on each local node |
178 | ||
179 | service vlan:: The main VLAN tag of this zone | |
180 | ||
9a4f3c95 AD |
181 | service vlan protocol:: allow to define a 802.1q (default) or 802.1ad service vlan type. |
182 | ||
ee6e18c4 TL |
183 | mtu:: Due to the double stacking of tags you need 4 more bytes for QinQ VLANs. |
184 | For example, you reduce the MTU to `1496` if you physical interface MTU is | |
185 | `1500`. | |
1556b768 | 186 | |
4e652aba | 187 | [[pvesdn_zone_plugin_vxlan]] |
ee6e18c4 TL |
188 | VXLAN Zones |
189 | ~~~~~~~~~~~ | |
1556b768 | 190 | |
ee6e18c4 TL |
191 | The VXLAN plugin will establish a tunnel (named overlay) on top of an existing |
192 | network (named underlay). It encapsulate layer 2 Ethernet frames within layer | |
193 | 4 UDP datagrams, using `4789` as the default destination port. You can, for | |
194 | example, create a private IPv4 VXLAN network on top of public internet network | |
195 | nodes. | |
196 | This is a layer2 tunnel only, no routing between different VNets is possible. | |
1556b768 | 197 | |
ee6e18c4 | 198 | Each VNet will have use specific VXLAN id from the range (1 - 16777215). |
1556b768 | 199 | |
ee6e18c4 | 200 | Specific EVPN configuration options: |
1556b768 | 201 | |
4e652aba TL |
202 | peers address list:: A list of IPs from all nodes through which you want to |
203 | communicate. Can also be external nodes. | |
204 | ||
205 | mtu:: Because VXLAN encapsulation use 50bytes, the MTU need to be 50 bytes | |
206 | lower than the outgoing physical interface. | |
1556b768 | 207 | |
4e652aba | 208 | [[pvesdn_zone_plugin_evpn]] |
ee6e18c4 TL |
209 | EVPN Zones |
210 | ~~~~~~~~~~ | |
1556b768 | 211 | |
ee6e18c4 | 212 | This is the most complex of all supported plugins. |
1556b768 | 213 | |
ee6e18c4 TL |
214 | BGP-EVPN allows one to create routable layer3 network. The VNet of EVPN can |
215 | have an anycast IP-address and or MAC-address. The bridge IP is the same on each | |
216 | node, with this a virtual guest can use that address as gateway. | |
1556b768 | 217 | |
ee6e18c4 TL |
218 | Routing can work across VNets from different zones through a VRF (Virtual |
219 | Routing and Forwarding) interface. | |
1556b768 | 220 | |
ee6e18c4 | 221 | Specific EVPN configuration options: |
1556b768 | 222 | |
9f819242 | 223 | VRF VXLAN tag:: This is a vxlan-id used for routing interconnect between vnets, |
ee6e18c4 | 224 | it must be different than VXLAN-id of VNets |
1556b768 | 225 | |
ee6e18c4 TL |
226 | controller:: an EVPN-controller need to be defined first (see controller |
227 | plugins section) | |
1556b768 | 228 | |
9f819242 TL |
229 | VNet MAC address:: A unique anycast MAC address for all VNets in this zone. |
230 | Will be auto-generated if not defined. | |
a6af82c7 | 231 | |
9f819242 TL |
232 | Exit Nodes:: This is used if you want to define some proxmox nodes, as exit |
233 | gateway from evpn network through real network. The configured nodes will | |
234 | announce a default route in the EVPN network. | |
a6af82c7 | 235 | |
9f819242 TL |
236 | MTU:: because VXLAN encapsulation use 50 bytes, the MTU needs to be 50 bytes |
237 | lower than the maximal MTU of the outgoing physical interface. | |
1556b768 AD |
238 | |

a6af82c7 AD |
240 | [[pvesdn_config_vnet]] |
241 | VNets | |
242 | ----- | |
243 | ||
244 | A `VNet` is in its basic form just a Linux bridge that will be deployed locally | |
245 | on the node and used for Virtual Machine communication. | |
246 | ||
247 | VNet properties are: | |
248 | ||
249 | ID:: a 8 characters ID to name and identify a VNet | |
250 | ||
251 | Alias:: Optional longer name, if the ID isn't enough | |
252 | ||
253 | Zone:: The associated zone for this VNet | |
254 | ||
255 | Tag:: The unique VLAN or VXLAN id | |
256 | ||
257 | VLAN Aware:: Allow to add an extra VLAN tag in the virtual machine or | |
258 | container vNIC configurations or allow the guest OS to manage the VLAN's tag. | |
259 | ||
260 | [[pvesdn_config_subnet]] | |
261 | ||
3093e62d TL |
262 | Sub-Nets |
263 | ~~~~~~~~ | |
264 | ||
265 | A sub-network (subnet or sub-net) allows you to define a specific IP network | |
266 | (IPv4 or IPv6). For each VNET, you can define one or more subnets. | |
1556b768 | 267 | |
3093e62d | 268 | A subnet can be used to: |
a6af82c7 | 269 | |
3093e62d TL |
270 | * restrict IP-addresses you can define on a specific VNET |
271 | * assign routes/gateway on a VNET in layer 3 zones | |
272 | * enable SNAT on a VNET in layer 3 zones | |
273 | * auto assign IPs on virtual guests (VM or CT) through IPAM plugin | |
274 | * DNS registration through DNS plugins | |
a6af82c7 | 275 | |
3093e62d TL |
276 | If an IPAM server is associated to the subnet zone, the subnet prefix will be |
277 | automatically registered in the IPAM. | |
a6af82c7 AD |
278 | |
279 | ||
280 | Subnet properties are: | |
281 | ||
282 | ID:: a cidr network address. Ex: 10.0.0.0/8 | |
283 | ||
284 | Gateway:: ip address for the default gateway of the network. | |
3093e62d TL |
285 | On layer3 zones (simple/evpn plugins), it'll be deployed on the vnet. |
286 | ||
a6af82c7 | 287 | Snat:: Optional, Enable Snat for layer3 zones (simple/evpn plugins) for this subnet. |
3093e62d TL |
288 | The subnet source ip will be natted to server outgoing interface/ip. |
289 | On evpn zone, it's done only on evpn gateway-nodes. | |
a6af82c7 AD |
290 | |
291 | Dnszoneprefix:: Optional, add a prefix to domain registration, like <hostname>.prefix.<domain> | |

a6af82c7 AD |
294 | [[pvesdn_config_controllers]] |
295 | Controllers | |
296 | ----------- | |
297 | ||
298 | Some zone types need an external controller to manage the VNet control-plane. | |
299 | Currently this is only required for the `bgp-evpn` zone plugin. | |

303 | ~~~~~~~~~~~~~~~ | |
1556b768 | 304 | |
ee6e18c4 TL |
305 | For `BGP-EVPN`, we need a controller to manage the control plane. |
306 | The currently supported software controller is the "frr" router. | |
307 | You may need to install it on each node where you want to deploy EVPN zones. | |
1556b768 AD |

850 | Apply the configuration on the main SDN web-interface panel to create VNets |
851 | locally on each nodes and generate the FRR config. | |
1556b768 | 852 | |
ee6e18c4 | 853 | Create a Debian-based Virtual Machine (vm1) on node1, with a vNIC on `myvnet1'. |
1556b768 | 854 | |
ee6e18c4 | 855 | Use the following network configuration for this VM: |
1556b768 AD |
856 | |
857 | ---- | |
858 | auto eth0 | |
859 | iface eth0 inet static | |
860 | address 10.0.1.100/24 | |
861 | gateway 10.0.1.1 #this is the ip of the vnet1 | |
862 | mtu 1450 | |
863 | ---- | |
864 | ||
ee6e18c4 TL |
865 | Create a second Virtual Machine (vm2) on node2, with a vNIC on the other VNet |
866 | `myvnet2'. | |
867 | ||
868 | Use the following network configuration for this VM: | |
869 | ||
1556b768 AD |
870 | ---- |
871 | auto eth0 | |
872 | iface eth0 inet static | |
873 | address 10.0.2.100/24 | |
874 | gateway 10.0.2.1 #this is the ip of the vnet2 | |
875 | mtu 1450 | |

879 | Then, you should be able to ping vm2 from vm1, and vm1 from vm2. | |
880 | ||
ee6e18c4 | 881 | If you ping an external IP from 'vm2' on the non-gateway 'node3', the packet |
a6af82c7 | 882 | will go to the configured 'myvnet2' gateway, then will be routed to the exit |
ee6e18c4 TL |
883 | nodes ('node1' or 'node2') and from there it will leave those nodes over the |
884 | default gateway configured on node1 or node2. | |
1556b768 | 885 | |
ee6e18c4 TL |
886 | NOTE: Of course you need to add reverse routes for the '10.0.1.0/24' and |
887 | '10.0.2.0/24' network to node1, node2 on your external gateway, so that the | |
888 | public network can reply back. | |

890 | If you have configured an external BGP router, the BGP-EVPN routes (10.0.1.0/24 |
891 | and 10.0.2.0/24 in this example), will be announced dynamically. |
