[00:21] <johunt> hitting a problem where my vms are not honoring accept_ra sysctls defined in /proc. it looks like netplan should? based on some code default to whatever the value is in the kernel, but that does not appear to get passed to systemd-networkd.
[00:21] <johunt> i see this code
[00:21] <johunt> netdef->accept_ra = NETPLAN_RA_MODE_KERNEL;
[10:12] <slyon> johunt: Yes, if accept-ra is not set in your netplan config, systemd-networkd will use it's defaults: https://systemd.network/systemd.network.html#IPv6AcceptRA=
[10:12] <slyon> "The default is to disable RA reception for bridge devices or when IP forwarding is enabled, and to enable it otherwise. Cannot be enabled on bond devices and when link-local addressing is disabled."
[10:13] <slyon> If you're using VMs, bridges/IP forwarding might be in place, so you could try force-enabling it to accept RAs

[17:08] <johunt> sylon: thanks. yeah this is all a little confusing b/c i have the sysctls set on the machine to set accept_ra and autoconf to 0, but systemd seems to know better than that...
[17:09] <johunt> i guess i was hoping that if there was no specific netplan config param set for accept_ra then it or systemd would default to the sysctl values...
