From c6a1ccca4fe5c42e2a435e5335c701c112242bd0 Mon Sep 17 00:00:00 2001 From: nl6720 Date: Fri, 9 Jul 2021 17:01:57 +0300 Subject: configs/releng/airootfs/etc/systemd/network/: move RouteMetric= from [DHCPv6] to [IPv6AcceptRA] systemd moved the option. See https://github.com/systemd/systemd/commit/8ebafba9f987c21aa5787c8767f2e390b4ec0bc5 . Implements #123. Document in comments why the route metrics need to be set (because of https://github.com/systemd/systemd/issues/17698 ) and use the same metric values as NetworkManager. https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/main/src/core/devices/nm-device.c Additionally remove RouteMetric from configs/baseline/airootfs/etc/systemd/network/20-ethernet.network. There is only one networkd configuration file in baseline, meaning, there are no other routes. --- .../releng/airootfs/etc/systemd/network/20-ethernet.network | 11 ++++++++--- configs/releng/airootfs/etc/systemd/network/20-wlan.network | 11 ++++++++--- configs/releng/airootfs/etc/systemd/network/20-wwan.network | 11 ++++++++--- 3 files changed, 24 insertions(+), 9 deletions(-) (limited to 'configs/releng/airootfs') diff --git a/configs/releng/airootfs/etc/systemd/network/20-ethernet.network b/configs/releng/airootfs/etc/systemd/network/20-ethernet.network index 142c591..88662a4 100644 --- a/configs/releng/airootfs/etc/systemd/network/20-ethernet.network +++ b/configs/releng/airootfs/etc/systemd/network/20-ethernet.network @@ -9,8 +9,13 @@ Name=eth* DHCP=yes IPv6PrivacyExtensions=yes +# systemd-networkd does not set per-interface-type default route metrics +# https://github.com/systemd/systemd/issues/17698 +# Explicitly set route metric, so that Ethernet is preferred over Wi-Fi and Wi-Fi is preferred over mobile broadband. +# Use values from NetworkManager.
