| 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 | ||
| 19 | For BUM traffic (broadcast / unknown unicast traffic, multicast), | |
| 20 | we have 3 differents vxlan setup modes : multicast, unicast, bgp-evpn | |

| 24 | multicast mode | |
| 25 | ^^^^^^^^^^^^^^ | |
| 26 | ||
| 27 | This scenario relies in head end replication, meaning that end host in case | |
| 28 | of not having any entry for the destination MAC address will send out an ARP | |
| 29 | to other devices / VTEPs in the VXLAN network. | |
| 30 | This is done by sending the request to the VXLAN multicast group, | |
| 31 | remote VTEPs will get the packet and answer accordingly direct to the originating VTEP. | |

| 150 | unicast mode | |
| 151 | ^^^^^^^^^^^^ | |
| 152 | ||
| 153 | We can replace multicast by head-end replication of BUM frames to a statically configured lists of remote VTEPs. | |
| 154 | The VXLAN is defined without a remote multicast group. | |
| 155 | Instead, all the remote VTEPs are associated with the all-zero address: | |
| 156 | a BUM frame will be duplicated to all these destinations. | |
| 157 | The VXLAN device will still learn remote addresses automatically using source-address learning. | |

| 284 | ^^^^^^^^ | |
| 285 | ||
| 286 | VTEPs use control plane learning/distribution via BGP for remote MAC addresses instead of data plane learning. | |
| 287 | VTEPs have the ability to suppress ARP flooding over VXLAN tunnels. | |
| 288 | ||
| 289 | The control plane used here is FRR, a bgp routing software. | |
| 290 | Each node in the proxmox cluster peer with each others nodes. | |
| 291 | For bigger networks, or multiple proxmox clusters, | |
| 292 | it's possible to use external bgp route reflector servers. | |

| 853 | VXLAN layer3 routing with anycast gateway | |
| 854 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 855 | ||
| 856 | With this need, each vmbr bridge will be the gateway for the vm. | |
| 857 | Same vmbr on different node, will have same ip address and same mac address, | |
| 858 | to have working vm live migration and no network disruption. | |
| 859 | ||
| 860 | VXLAN layer3 routing only work with FRR and non-aware bridge. | |
| 861 | (vlan aware bridge support is buggy currently). | |

| 877 | asymmetric model | |
| 878 | ^^^^^^^^^^^^^^^^ | |
| 879 | ||
| 880 | This is the simplest mode. To get it work, all vxlan need to be defined on all nodes. | |
| 881 | ||
| 882 | The asymmetric model allows routing and bridging on the VXLAN tunnel ingress, | |
| 883 | but only bridging on the egress. | |
| 884 | This results in bi-directional VXLAN traffic traveling on different VNIs | |
| 885 | in each direction (always the destination VNI) across the routed infrastructure. | |

| 1112 | symmetric model | |
| 1113 | ^^^^^^^^^^^^^^^ | |
| 1114 | ||
| 1115 | With this model, you don't need to have all vxlan on all nodes. | |
| 1116 | This model will also be needed to route traffic to an external router. | |
| 1117 | ||
| 1118 | The symmetric model routes and bridges on both the ingress and the egress leafs. | |
| 1119 | This results in bi-directional traffic being able to travel on the same VNI, hence the symmetric name. | |
| 1120 | However, a new specialty transit VNI is used for all routed VXLAN traffic, called the L3VNI. | |
| 1121 | All traffic that needs to be routed will be routed onto the L3VNI, tunneled across the layer 3 Infrastructure, | |
| 1122 | routed off the L3VNI to the appropriate VLAN and ultimately bridged to the destination. | |
| 1123 | ||
| 1124 | 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. | |
