Setup DSL connection via netplan?

Question

I haven't seen any options to setup up DSL connection in /etc/netplan?
I know it's possible via pppoeconf, but I'm not sure how to modify the dsl-provider file/name (I need to setup for 2 different providers), so that it will still use it on boot time.

netplan does not directly support PPPoE connections today (netplan 0.105). There are two possible solutions using the supported tools in Ubuntu main.

• I use a networkd-dispatcher script in /etc/networkd-dispatcher/routable.d which starts the ppp connection whenever the ethernet device comes up:

  #!/bin/sh
  set -e
  if [ "$IFACE" != wan ]; then
          exit 0
  fi
  pppd call centurylink
  sleep 5
  ip route change default dev ppp0 advmss 1482
  

  I then have an additional script linked from each of /etc/networkd-dispatcher/{degraded,dormant,no-carrier,off}.d/ which stops it when it goes down:

  #!/bin/sh
  set -e
  if [ "$IFACE" != wan ]; then
          exit 0
  fi
  if [ -e /run/ppp-centurylink.pid ]; then
          pid=$(cat /run/ppp-centurylink.pid)
          kill "$pid"
  fi
  

  This approach connects the ppp configuration you have created (via pppoeconf or other means) to networkd.

• You can configure your PPPoE connection directly in NetworkManager.
