systemd 232 debian stretch 9.1 Hi,
I configure my ip stack with systemd-networkd. I do have a dual stack (v4 and v6). There is a router advertisement on fd69:620:600:b00:: and on 2001:620:600:b00:: and the ipv6 choosed is on a other network fd69:620:600:11:: The problem is that my ip configuration differs between the one I get after a reboot and the one I get after a "systemctl restart systemd-networkd". Do you have any idea what the problem could be or what to do to troubleshoot it ? Regards. cED ------------------ The config is: [Match] Name=ens192 [Network] DHCP=no Address=10.194.11.42/24 Gateway=10.194.11.1 IPv6AcceptRA=false Address=fd69:620:600:11:250:56ff:feb6:26b9/64 Gateway=fd69:620:600:11::1 Domains=unige.ch DNS=2001:620:600:4::6 DNS=2001:620:4::32 DNS=2001:620:600:8::7 When I do a systemctl restart systemd-network, the setup does not show any ip with the …:b00:: subnet. # networkctl status ● State: routable Address: 10.194.11.42 on ens192 fd69:620:600:11:250:56ff:feb6:26b9 on ens192 fe80::250:56ff:feb6:26b9 on ens192 Gateway: 10.194.11.1 (Cisco Systems, Inc) on ens192 fd69:620:600:11::1 (Cisco Systems, Inc) on ens192 fe80::5:73ff:fea0:d4 (Cisco Systems, Inc) on ens192 fe80::5:73ff:fea0:d5 (Cisco Systems, Inc) on ens192 DNS: 2001:620:600:4::6 2001:620:4::32 2001:620:600:8::7 Search Domains: unige.ch After a reboot, the networkctl status shows …:b00: subnet. # networkctl status ● State: routable Address: 10.194.11.42 on ens192 2001:620:600:b00:250:56ff:feb6:26b9 on ens192 --HERE fd69:620:600:11:250:56ff:feb6:26b9 on ens192 fd69:620:600:b00:250:56ff:feb6:26b9 on ens192 --HERE fe80::250:56ff:feb6:26b9 on ens192 Gateway: 10.194.11.1 (Cisco Systems, Inc) on ens192 fd69:620:600:11::1 (Cisco Systems, Inc) on ens192 fe80::5:73ff:fea0:d4 (Cisco Systems, Inc) on ens192 fe80::5:73ff:fea0:d5 (Cisco Systems, Inc) on ens192 DNS: 2001:620:600:4::6 2001:620:4::32 2001:620:600:8::7 Search Domains: unige.ch I have disabled other way of configuring the network # systemctl | grep -i netwo systemd-networkd.service loaded active running Network Service systemd-resolved.service loaded active running Network Name Resolution systemd-networkd.socket loaded active running Network Service Netlink Socket network-online.target loaded active active Network is Online network-pre.target loaded active active Network (Pre) network.target loaded active active Network # systemctl status networking ● networking.service - Raise network interfaces Loaded: loaded (/lib/systemd/system/networking.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:interfaces(5)
