Dobry den, mam problem s konfiguraciou ipv6. Mam nastavenych 9 dalsich ipv6 adries na eth0 a iba 2 z nich funguju. prideleny mam range a:4f8:190:2405:: / 64 (dhcp v konfiguracii eth0 si nevsimajte :) )

Funguju iba tie, ktore maju v route Ref nenulovu hodnotu. V manualoch som sa docital iba toto: Ref: Number of references to this route. Co nie je moc velavravne :)

Vedel by niekto poradit co tomu moze byt? Dakujem pekne

Já bych začal tím že bych všechny /128 změnil na /64.
K tomu úplně nevidím důvod, bohatě by mělo stačit dát délku prefixu té hlavní adrese.
Já už tu vlastně ani nejsem. Abclinuxu umřelo.

Místo výstupů 14 let obsolentních utilit raději ukažte výstup "ip addr show" a "ip route show", ať se můžeme podívat, jak ta konfigurace opravdu vypadá. A když říkám výstupy, myslím tím skutečné výstupy příkazů, ne náhodně obfuskované.

Přesně tak. Bez toho se to dost blbě čte.
