radvd[31898]: AdvValidLifeTime must be greater than AdvPreferredLifetime in /etc/radvd.conf, line 19
This happens with the following configuration:
vyos@vyos# show service router-advert
interface eth0.20 {
name-server 2001:4860:4860::8888
prefix ::/64 {
valid-lifetime 7200
}
}A validator should be added to avoid this problem
