## my requirement ##
# traffic arriving at a particular interface, fysical or vlan should
# also be answered via that interface
# Initionall version at server install (not used) written by 'subiquity'


# Initionall version after Ubuntu server install (completely modified) written by 'subiquity'

## ISSUES ##
# 1) So I did not define a server wide default gateway ....
# .... however that is not true if enp5s0 becomes active ....
# .... I simply do not know how to assign a routing and routing-policy to
# an dhcp provided address
# 2) The trunk is a container for vlans, it does not have an address ...
# .... however I had to give it a dummy address to make this file work

## Define the network
network:
  version: 2
  renderer: networkd


## Define Ethernet ports
  ethernets:


# Define the 2.5G interface
    enp5s0:
      dhcp4: true # default is off
      # don't wait for it to come up during boot
      optional: true
      nameservers:
        addresses:
        - 8.8.8.8
        - 1.0.0.1

# Define the ^startup interface^
#  ethernets:
    enp3s0f0:
      dhcp4: no
      dhcp6: no
      addresses:
      - 192.168.1.200/24
      routes:
      - to: default # could be 0/0 or 0.0.0.0/0 optionally
        via: 192.168.1.1
#       - to: default # could be ::/0 optionally
#         via: cf02:de:ad:be:ef::2

        - 1.0.0.1
#   nameserver domain(s)
#        Search:

# Define the trunk (2e 10G)
    enp3s0f1:
      addresses:
      - 9.9.9.9/32 # dummy! the trunk itself has not address, however that does not work
#    trunk:
#      match:  # does not work
#        name: enp3s0f1
#      set-name: trunk1 # requires match (on mac !!??)


## Define the vlans

# Define vlan100 (vm-managment)
  vlans:
    enp3s0f1.100:
      id: 100
      link: enp3s0f1
      addresses:
      - 192.168.100.10/24
      routes:
      - to: default
        via: 192.168.100.1
        on-link: true
        table: 100
#        metric: 100
