Digi no responde a DHCPv6 solicits por concesión previa no expirada

Tengo router propio VyOS. Hace unas dos semanas estuve haciendo pruebas cambiando temporalmente al router de Digi porque me había dejado de funcionar el teléfono fijo. Solventé eso creando una VLAN 11, aunque eso no viene al caso ahora. Al volver a VyOS y reiniciar un par de veces, obtuve IPv6 pero se perdió rápidamente.

Digi no respondía a los DHCPv6 solicits:

% tcpdump -r dhcpv6_solicit_sin_respuesta.pcap                                                                                     [0]

Lo que tenía asignado en la interfaz pppoe0 era algo así:

25: pppoe0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc fq_codel state UNKNOWN group default qlen 3
    link/ppp 
    inet 79.116.XXX.XXX peer 10.0.35.9/32 scope global pppoe0
       valid_lft forever preferred_lft forever
    inet6 fe80::f185:62ff:fe44:59e8/64 scope link 
       valid_lft forever preferred_lft forever
    inet6 fe80::XXXX:XXXX:XXXX:XXXX peer fe80::1/128 scope link 
       valid_lft forever preferred_lft forever

No recuerdo cuál era fe80::XXXX:XXXX:XXXX:XXXX, pero era aleatoria, no relacionada con una MAC.

Mirando en Internet, encontré esto:

That's what you've asked it to do.

IP6CP (the IPv6 network control protocol in PPP) does not negtioate
addresses or prefixes.  That is left for SLAAC or DHCPv6.  All it does
negotiate is the interface identifiers, i.e. the lower 64 bits of the
address.    This is also documented in the pppd man page.  So you need
to run either SLAAC or DHCPv6 on top of the PPP link if you want a
global address for it.  Although you probably don't need it...

Note that, just like IPv4 addresses, your ISP may choose to force you to
use a specific interface identifier.  So any specific setting you use
may be rejected by the other end and cause a failure.  It obviously did
not in your case, but that's just luck.  I would not recommend end users
setting specific interface identifiers.  Using "+ipv6" (and optionally
"noip" if you don't want dual stack) should be all that's necessary.

We had to force interface identifiers for our users because it turned
out that the DHCPv6 server would use this to match its leases in
addition to the DUID.  So if your PPP link went down and came up with a
new interface identifier (which is the Linux default at least), then the
DHCPv6 server would refuse any requests from that user until the lease
expired (unless the DHCPv6 client had freed the lease before the link
went down, shich of course will not happen in the common case).  The
solution was to issue specific per-user interface identifiers.

En este momento tenía DHCP6c desactivado:

sudo systemctl stop dhcp6c@pppoe0

Edité /etc/ppp/options y añadí el interface identifier de IPV6CP del router de Digi en formato ipv6. No quiero ponerlo aquí por privacidad, pero si por ejemplo, fuese éste:

ab:cd:ef:gh:ij:kl:mn:op

… añadimos esto:

+ipv6
ipv6 ::abcd:efhg:ijkl:mnop

Reiniciamos la interfaz pppoe0:

vyos@vyos# run disconnect interface pppoe0 
Interface pppoe0: disconnecting...
[edit]
vyos@vyos# run connect interface pppoe0 
Interface pppoe0: connecting...

pppoe0 nos quedará así:

25: pppoe0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc fq_codel state UNKNOWN group default qlen 3
    link/ppp 
    inet 79.116.X.X peer 10.0.35.9/32 scope global pppoe0
       valid_lft forever preferred_lft forever
    inet6 fe80::f185:62ff:fe44:59e8/64 scope link 
       valid_lft forever preferred_lft forever
    inet6 fe80::abcd:efgh:ijkl:mnop peer fe80::1/128 scope link 
       valid_lft forever preferred_lft forever

Los últimos dígitos de fe80::abcd:efgh:ijkl:mnop son el interface identifier.

Haciendo tcpdump veo que me hay tráfico de mi home assistant intentando salir por ppppoe0.

El tráfico llega a pppoe0. No pasa de ahí porque todavía no se han hecho DHCPv6 solicits (dhcp6c sigue apagado) ni asignado IPv6 a mi LAN. Sin embargo, el hecho de que el tráfico llegue a pppoe0 significa que Digi está enrutando (a 2a0c:5a83:4000:XXXX::/56), y que todavía tiene una concesión DHCP en vigor del momento en el que conecté temporalmente el router de Digi.

Ahora hice un DHCP release para liberar 2a0c:5a83:4000:XXXX::/56. Que yo sepa no es posible con dhp6c, así que empleé otro cliente, dhclient. Normalmente almacena los leases en el fichero /var/lib/dhcp/dhclient6.leases. Edité el fichero en esa ruta (que sólo contenía default-duid) y añadí lo siguiente:

default-duid "\000\001\000\001\025y\241\337\224(o\023\203\033";
lease6 {
  interface "pppoe0";
  ia-na 00:00:00:01 {
    starts 1458668291;
    renew 43200;
    rebind 69120;
    iaaddr 2a0c:5a83:40ff:ffff::bc1a:ce7d {
      starts 0;
      preferred-life 0;
      max-life 0;
    }
  }
  ia-pd 00:00:03:e8 {
    starts 1458668291;
    renew 43200;
    rebind 69120;
    iaprefix 2a0c:5a83:4000:XXXX::/56 {
      starts 1458668291;
      preferred-life 0;
      max-life 0;
    }
  }
  option dhcp6.client-id 0:1:0:1:15:79:a1:df:ab:cd:ef:gh:ij:kl;

}

He copiado los datos de dhcp.client-id y dhcp6.server-id de la captura espía.

En este momento intenté hacer el release:

Falla porque ha arrancado automáticamente dhcp6c. Arranca automáticamente al cabo de un tiempo aunque lo haya parado previamente. Lo paramos nuevamente y reintentamos:

En tcpdump vi ver el release:

Volví a tirar y levantar pppoe:

Vi en tcpdump lo siguiente:

00:34:55.221239 IP6 fe80::f185:62ff:fe44:59e8.dhcpv6-client > ff02::1:2.dhcpv6-server: dhcp6 solicit

00:35:12.487115 IP6 fe80::1 > ip6-allnodes: ICMP6, router advertisement, length 16

Quien estaba mandando la petición es la otra ipv6 de pppoe0, fe80::f185:62ff:fe44:59e8/64. No sé qué pinta, así que la eliminé:

vyos@vyos# sudo ip -6 address delete fe80::f185:62ff:fe44:59e8/64 dev pppoe0

Ahora, por fin, respondió el servidor de Digi fe80::1 con un dhcp6 reply, y empecé a ver tráfico de mi PC:
