VxLAN with static BUM

Hint

For details on VxLAN on Linux see also this nice blog post Unicast with static flooding by Vincent Bernat.

This example configures a bridge with a VxLAN link attached. Static FDB entries are configured for BUM traffic:

configure eth0 with an IP address used for the VTEP
create a bridge interface br0 and configure the IP address 192.0.2.1
create a VxLAN tunnel vxlan100
add vxlan100 to the bridge br0
add some static FDB entries on vxlan100 for static flooding
set all interface link states to up

ifstate

interfaces:
- name: eth0
  addresses:
  - 198.51.100.1/24
  link:
    state: up
    kind: physical
- name: br0
  addresses:
    - 192.0.2.1/24
  link:
    kind: bridge
    state: up
- name: vxlan100
  link:
    kind: vxlan
    vxlan_id: 100
    vxlan_port: 4789
    vxlan_local: 198.51.100.1
    master: br0
    state: up
  fdb:
    - lladdr: 00:00:00:00:00:00
      dst: 198.51.100.2
      port: 4789
    - lladdr: 00:00:00:00:00:00
      dst: 198.51.100.3
      port: 4789

manually

# configure eth0
ip address add 198.51.100.2/31 dev eth0
ip link set dev eth0 up

# configure br0
ip link add name br0 type bridge
ip link set dev br0 up
ip address add 192.0.2.1/24 dev br0

# configure vxlan100
ip link add vxlan100 type vxlan id 100 local 198.51.100.2 dstport 4789
ip link set dev vxlan100 master br0
ip link set dev vxlan100 up

# add static flooding entries to FDB
bridge fdb append 00:00:00:00:00:00 dev vxlan100 dst 198.51.100.2 port 4789
bridge fdb append 00:00:00:00:00:00 dev vxlan100 dst 198.51.100.3 port 4789
