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.

493 VXLAN layer3 routing with anycast gateway
494 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
495
496 With this need, each vmbr bridge will be the gateway for the vm.
497 Same vmbr on different node, will have same ip address and same mac address,
498 to have working vm live migration and no network disruption.
499
500 VXLAN layer3 routing only work with FRR and non-aware bridge.
501 (vlan aware bridge support is buggy currently).

517 asymmetric model
518 ^^^^^^^^^^^^^^^^
519
520 This is the simplest mode. To get it work, all vxlan need to be defined on all nodes.
521
522 The asymmetric model allows routing and bridging on the VXLAN tunnel ingress,
523 but only bridging on the egress.
524 This results in bi-directional VXLAN traffic traveling on different VNIs
525 in each direction (always the destination VNI) across the routed infrastructure.

752 symmetric model
753 ^^^^^^^^^^^^^^^
754
755 With this model, you don't need to have all vxlan on all nodes.
756 This model will also be needed to route traffic to an external router.
757
758 The symmetric model routes and bridges on both the ingress and the egress leafs.
759 This results in bi-directional traffic being able to travel on the same VNI, hence the symmetric name.
760 However, a new specialty transit VNI is used for all routed VXLAN traffic, called the L3VNI.
761 All traffic that needs to be routed will be routed onto the L3VNI, tunneled across the layer 3 Infrastructure,
762 routed off the L3VNI to the appropriate VLAN and ultimately bridged to the destination.
763
764 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.
