Bird Interference with systemd-networkd

Hi, on one of my systems, I'm migrating from ifupdown2 to systemd-networkd. The scenario is an wireguard-overlay running OSPF and BGP using bird 2.0.7, and the underlay/public network interface being configured using DHCP and SLAAC. During the setup, I ran into problems with systemd-networkd, which changed the interface state into "Could not set NDisc route: Connection timed out" and loosing the Default WAN Route some time after bird installed the routes. This seems like a problem on a netlink-level etc. - likely on the networkd side, but I wonder if someone on this list had a similar problem. Bugreport and Discussion is ongoing over at systemd github: https://github.com/systemd/systemd/issues/19738 Thanks! Marvin
