--- Begin Message ---Package: systemd Version: 230-2 Severity: normal According on the systemd.network manual page: IPv6AcceptRouterAdvertisements= Force the setting of the accept_ra ... Takes a boolean. ... note that systemd's setting of 1 corresponds to kernel's setting of 2. This documented behavior is not the behavior that I am seeing. IPv6AcceptRouterAdvertisements always results in accept_ra=1. Since this system also performs routing (forwarding is enabled), this means that router advertisements are ignored. The interface in question is a bridge interface named br_32. The contents of /etc/systemd/network/br_32.network are ===== [Match] Name=br_32 [Network] IPv6AcceptRouterAdvertisements=yes IPv6PrivacyExtensions=yes ===== The following sequence of commands show what I'm experiencing. ===== # systemctl restart systemd-networkd.service # sysctl net.ipv6.conf.br_32.accept_ra net.ipv6.conf.br_32.accept_ra = 1 # sysctl -w net.ipv6.conf.br_32.accept_ra=2 # sysctl net.ipv6.conf.br_32.accept_ra net.ipv6.conf.br_32.accept_ra = 2 # systemctl restart systemd-networkd.service # sysctl net.ipv6.conf.br_32.accept_ra net.ipv6.conf.br_32.accept_ra = 1 ===== So systemd-networkd does not set accept_ra=2 as indicated in the manual page and as required in my network configuation. I can manually set accept_ra=2 for that interace with `sysctl -w`, and then everything works correctly (RAs are accepted and SLAAC works). However, restarting systemd-networkd sets accept_ra back to 1, disabling acceptance of future RAs. I've also tried setting IPv6AcceptRouterAdvertisements=2. Unfortunately, this is unsupported syntax as it "Takes a boolean." So I'm unable to set or keep accept_ra=2 via systemd-networkd, and I can't set it via /etc/sysctl.conf since systemd-networkd.service will clobber the sysctl.conf setting when it runs. Please fix systemd-networkd so that IPv6AcceptRouterAdvertisements behaves as described in the manual page. -- Package-specific info: -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (990, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.6.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages systemd depends on: ii adduser 3.114 ii libacl1 2.2.52-3 ii libapparmor1 2.10-4 ii libaudit1 1:2.5.2-1 ii libblkid1 2.28-5 ii libc6 2.22-11 ii libcap2 1:2.25-1 ii libcap2-bin 1:2.25-1 ii libcryptsetup4 2:1.7.0-2 ii libgcrypt20 1.7.0-2 ii libgpg-error0 1.22-2 ii libkmod2 22-1.1 ii liblzma5 5.1.1alpha+20120614-2.1 ii libmount1 2.28-5 ii libpam0g 1.1.8-3.3 ii libseccomp2 2.3.1-2 ii libselinux1 2.5-3 ii libsystemd0 230-2 ii mount 2.28-5 ii util-linux 2.28-5 Versions of packages systemd recommends: ii dbus 1.10.8-1 ii libpam-systemd 230-2 Versions of packages systemd suggests: ii systemd-container 230-2 ii systemd-ui 3-4 Versions of packages systemd is related to: ii udev 230-2 -- Configuration Files: /etc/systemd/resolved.conf changed [not included] /etc/systemd/timesyncd.conf changed [not included] -- no debconf information
