Nov 14 20:11:39 chassiron dhcpcd[28004]: pppoe0: failed to rebind prior delegation
Hmmm, that is a slight cause for concern.
Did it send out a rebind request that looks ok?
I guess it did not, the only thing I see on
tcpdump -n -p -i pppoe0 port 546 or port 457
is:
20:11:41.891320 PPPoE [ses 0x21d7] IP6 fe80::230:88ff:fe04:63c9.547 > fe80::43e:1a93:9ba2:3ac9.546: dhcp6 advertise
20:11:41.902095 PPPoE [ses 0x21d7] IP6 fe80::230:88ff:fe04:63c9.547 > fe80::43e:1a93:9ba2:3ac9.546: dhcp6 reply
Is the delegation you got the same as the previous one?
Yes, but it's a static delegation so I wouldn't expect something different.
I don't know what the remote end expects, maybe when a new pppoe session
starts, dhcp state is reset ? This would be consustent with the IPv6
route for my prefix being lost ...
