Comment 7 for bug 1965883

Also when I do

sudo radvdump
sudo ip link set ens8 down
sudo ip link set ens8 up

I receive the advertisement in just 2-3-4 seconds

same with
sudo radvdump
sudo ip link set ens8 down
sudo systemctl restart systemd-networkd.service

interface ens8
{
        AdvSendAdvert on;
        # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump
        AdvManagedFlag off;
        AdvOtherConfigFlag off;

        AdvDefaultLifetime 65535;
        AdvHomeAgentFlag off;
        AdvDefaultPreference medium;
        AdvSourceLLAddress on;

                AdvPreferredLifetime infinity; # (0xffffffff)
                AdvOnLink on;
