Je potřeba tam mít i RADVD?
Je nutné tam mít RADV; to bezpodmínečně. Bez toho IPv6 přece neexistuje. Nikoliv ovšem RADVD; ten je jenom jedna z možností. RADV snadno zajistí systemd-networkd. Já osobně používám systemd-networkd pro RADV, protože pro mě nemá smysl mít oddělený jednoúčelový RADVD, když systemd-networkd má všechnu konfiguraci na jednom místě.
Problém ale je, že systemd-networkd (man systemd.network) zatím implementuje jenom DHCPv4. Což je na houby, pokud jde o nějaké univerzální integrované řešení. Takže je to derivované řešení. Pro DHCPv6 používám ISC DHCP server. DHCPv4 zajistí systemd-networkd.
Otázka ovšem je, jestli je potřeba mít DHCPv6. Ten rozhodně není povinný. Spousta klientských zařízení ho dodnes pořádně neumí. (Android, looking at ya!) Síť klidně může vesele fungovat bez něj.

/etc/systemd/network/? Ale nerozumím tomu, kde je nakonfigurované RADV pro DHCPv6, které je nakonfigurované v ISC DHCP serveru, jestliže není nainstalován např. RADVD??

[IPV6PREFIXDELEGATION]Vůbec nemám ponětí, jestli to mám správně. Takovéhle mám tři WiFi a fungují.
[Match] MACAddress=[[censored: A]] # Fake anyway, udev + man systemd.link [Link] MTUBytes=2312 ARP=yes [Network] Description=Nahovno Address=[[censored: B]]:4::/64 Address=10.79.4.1/24 IPForward=yes IPv6AcceptRA=no IPv6PrefixDelegation=static IPv6ProxyNDP=no DHCP=no DHCPServer=yes IPv4ProxyARP=no IPv6DuplicateAddressDetection=0 # Probably not needed. IPv6PrivacyExtensions=no [Address] Address=[[censored: B]]:4::/64 # This *skips* DAD DuplicateAddressDetection=none # Probably not needed. ManageTemporaryAddress=no [IPv6Prefix] Prefix=[[censored: B]]:4::/64 [IPv6PrefixDelegation] OtherInformation=true RouterLifetimeSec=86400 DNS=[[censored: B]]:4:: DNSLifetimeSec=86400 [DHCPServer] EmitDNS=yes DNS=10.79.4.1 EmitNTP=yes NTP=10.79.4.1 EmitRouter=yes EmitTimezone=yes
Na tohle pozor: OtherInformation=true Bez DHCPv6 by to mělo být nastavené na false. U toho nevím, jak má vypadat; na ISC DHCPD to mám zhruba takto:
ddns-update-style interim;
ddns-updates on;
ddns-domainname "[[censored: C]]";
ddns-rev-domainname "ip6.arpa";
allow client-updates;
update-conflict-detection false;
update-optimization false;
authoritative;
option domain-name-servers whoknowswhat.[[censored: C]];
default-lease-time 86400;
allow leasequery;
key v6dhcpupdate {
algorithm hmac-md5;
secret "[[censored: H(ovnovole)]]";
}
zone h.a.l.b.d.e.r.o.s.n.e.c.ip6.arpa. {
primary localhost;
key v6dhcpupdate;
}
zone [[censored: C]]. {
primary localhost;
key v6dhcpupdate;
}
### ... lots of subnets here ... ###
subnet6 [[censored: B]]:4::/64 {
option dhcp6.name-servers [[censored: B]]:4::;
option dhcp6.sntp-servers [[censored: B]]:4::;
}
log-facility local7;
Spoiler Alert: Aktualizace DNS záznamů do ISC BIND nefunguje a nikdy nefungovala. (Je to sračka, kterou už asi tak 10+ let nikdo neopravoval a neudržoval (kromě pár segfaultů) a už před těmi 10 lety nefungovala.) Takže tam to nastavení sice je, ale nemá vůbec žádný význam; nefunguje to. Stroje na síti (kromě Androidu, který DHCPv6 neumí) se tam poctivě hlásí, ale ničeho tím nedosáhnou, protože je to rozbité. (Jo, pak se jeden diví, proč někdo někde používá to proprietární Cisco. Tak. Proto.)

Není to jenom nějaký detail kolem povolení NDP a ARP? Když se podíváš na sysctl -a a vygrepuješ název příslušných rozhraní, fyzických nebo virtuálních, je tam totéž?
