Hello,

I recently stumbled across the following section in the systemd-networkd
documentation for IPv6AcceptRA=:

"Note that kernel's implementation of the IPv6 RA protocol is always
disabled, regardless of this setting. [...]"

What does this mean in practice? Is the kernel's IPv6 RA implementation
disabled (by setting accept_ra=0?) when systemd-networkd is started?
Does it affect all network interfaces or just the ones managed
(configured) by systemd-networkd?

When I run other services in parallel like dhcpcd, how does networkd
affect them? When dhcpcd binds to dhcpv6 client port 546,
systemd-networkd fails to bind in case of a O-flag in the RA, but are
they also interfering with received RAs?

Thanks in advance for giving some insights.

Best regards,

Marc
