Change Details

Disabling an entire address family in an IPv6 enabled operating system/world actually adds more harm then good to VyOS. VyOS does not send out any RA if not configured explicitly thus VyOS behaves like any other Linux/Windows/Mac when it comes to networking. It only does what it's instructed to do. Reasons why this option is marked deprecated in 1.3 and removed in 1.4: - IPv6 is more then 20 years old - No RAs sent by VyOS if not told so - Disabling IPv6 but have services listen on an IPv6 address could cause all kind of config errors on reboots
