| 11 | VXLAN layer2 with vlan unware linux bridges | |
| 12 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 13 | ||
| 14 | VXLAN is an overlay network to carry Ethernet traffic over an existing IP network | |
| 15 | while accommodating a very large number of tenants. It is defined in RFC 7348. | |
| 16 | Each overlay network is known as a VXLAN Segment and identified by a unique | |
| 17 | 24-bit segment ID called a VXLAN Network Identifier (VNI). | |
| 18 | ||
| 47cf2d10 AD |
19 | VXLAN encapsulation add 50bytes overhead, so you need to increase mtu on your host |
| 20 | physical interfaces to 1550 at minimum. (or decrease mtu inside your vms to 1450) | |
| 21 | ||

22 | For BUM traffic (broadcast / unknown unicast traffic, multicast), |
| 23 | we have 3 differents vxlan setup modes : multicast, unicast, bgp-evpn | |

| 27 | multicast mode | |
| 28 | ^^^^^^^^^^^^^^ | |
| 29 | ||
| 30 | This scenario relies in head end replication, meaning that end host in case | |
| 31 | of not having any entry for the destination MAC address will send out an ARP | |
| 32 | to other devices / VTEPs in the VXLAN network. | |
| 33 | This is done by sending the request to the VXLAN multicast group, | |
| 34 | remote VTEPs will get the packet and answer accordingly direct to the originating VTEP. | |

| 165 | We can replace multicast by head-end replication of BUM frames to a statically configured lists of remote VTEPs. | |
| 166 | The VXLAN is defined without a remote multicast group. | |
| 167 | Instead, all the remote VTEPs are associated with the all-zero address: | |
| 168 | a BUM frame will be duplicated to all these destinations. | |
| 169 | The VXLAN device will still learn remote addresses automatically using source-address learning. | |

| 307 | VTEPs use control plane learning/distribution via BGP for remote MAC addresses instead of data plane learning. | |
| 308 | VTEPs have the ability to suppress ARP flooding over VXLAN tunnels. | |
| 309 | ||
| 310 | The control plane used here is FRR, a bgp routing software. | |
| 311 | Each node in the proxmox cluster peer with each others nodes. | |
| 312 | For bigger networks, or multiple proxmox clusters, | |
| 313 | it's possible to use external bgp route reflector servers. | |

523 | VXLAN layer3 routing with anycast gateway |
| 524 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 525 | ||
| 526 | With this need, each vmbr bridge will be the gateway for the vm. | |
| 527 | Same vmbr on different node, will have same ip address and same mac address, | |
| 528 | to have working vm live migration and no network disruption. | |
| 529 | ||
| 530 | VXLAN layer3 routing only work with FRR and non-aware bridge. | |
| 531 | (vlan aware bridge support is buggy currently). | |
| 532 | ||

533 | asymmetric model |
| 534 | ^^^^^^^^^^^^^^^^ | |
| 535 | ||
| 536 | This is the simplest mode. To get it work, all vxlan need to be defined on all nodes. | |
| 537 | ||
| 538 | The asymmetric model allows routing and bridging on the VXLAN tunnel ingress, | |
| 539 | but only bridging on the egress. | |
| 540 | This results in bi-directional VXLAN traffic traveling on different VNIs | |
| 541 | in each direction (always the destination VNI) across the routed infrastructure. | |

| 785 | symmetric model | |
| 786 | ^^^^^^^^^^^^^^^ | |
| 787 | ||
| 788 | With this model, you don't need to have all vxlan on all nodes. | |
| 789 | This model will also be needed to route traffic to an external router. | |
| 790 | ||
| 791 | The symmetric model routes and bridges on both the ingress and the egress leafs. | |
| 792 | This results in bi-directional traffic being able to travel on the same VNI, hence the symmetric name. | |
| 793 | However, a new specialty transit VNI is used for all routed VXLAN traffic, called the L3VNI. | |
| 794 | All traffic that needs to be routed will be routed onto the L3VNI, tunneled across the layer 3 Infrastructure, | |
| 795 | routed off the L3VNI to the appropriate VLAN and ultimately bridged to the destination. | |
| 796 | ||
| 797 | A vrf is needed for the L3VNI, so all vmbr bridge need to be in the vrf if they want to be able to reach each others. | |

| 1150 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 1151 | Routing to outside need the symmetric model. | |
| 1152 | ||
| 1153 | 1 gateway node | |
| 1154 | ^^^^^^^^^^^^^^ | |
| 1155 | In this example, we'll use only 1 proxmox node as exit gateway. (node1) | |
| 1156 | This node have a simple default gw in the vrf to the external router (no bgp between router and node1) | |
| 1157 | and announce this default gw to other proxmox nodes. | |

| 1510 | multiple gateway nodes | |
| 1511 | ^^^^^^^^^^^^^^^^^^^^^^ | |
| 1512 | In this example, all nodes will be used as exit gateway. (But you can use only 2 nodes if you want) | |
| 1513 | All nodes have a simple default gw in the vrf to the external router (no bgp between router and node1) | |
| 1514 | and announce this default gw. | |
| 1515 | The external router have ecmp routes to all proxmox nodes.(balancing). | |
| 1516 | If the router send the packet to a wrong node (vm is not on this node), this node will route through | |
| 1517 | vxlan the packet to final destination. | |

| 1895 | If your external router don't support ecmp to reach multiple proxmox nodes, | |
| 1896 | you can setup an HA floating vip on proxmox nodes with vrrp | |
| 1897 | ||
| 1898 | I this example, we will setup an floating 172.16.0.10 ip on node1 and node2. | |
| 1899 | Node1 is the primary and failover to node2 in case of failure. | |
