I've been recently enabling IPV6 on all my server that got native IPv6 the only server I had it configured on before was my mail server.
Ever server the IPv6 is working fine except for one that got a werid issue on boot IPv6 doesn't work until I ping the gateway IP or randomly after about 5-10 mins after boot it starts working after that it seem to work fine.
Just wondering if anyone who understands IPv6 and networking better then me got any ideas what might be causing the issue.
I've included the relevant part of network config on Debian
iface ens192 inet6 static address 2a00:****:****:77:1:ea7:dead:beef/64 gateway fe80::1
