router-advert: radvd does not start when lifetime is improperly configured
Closed, ResolvedPublicBUG


radvd[31898]: AdvValidLifeTime must be greater than AdvPreferredLifetime in /etc/radvd.conf, line 19

This happens with the following configuration:

[email protected]# 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
