Comment (by cyrus):
OK, that sounds a bit strange. First of all, there is no difference as to
how ping6 and ssh do the neighbor lookup (in fact the kernel handles it
for both).
Similarly a STALE entry is per-se not problematic since it will become
active again automatically or at least should.
You mentioned fallback to IPv4 so I assume you are using some kind of DNS
inside your home for the ssh. Since you have disabled ra_management IPv6
addresses aren't learnt through DHCPv6 so it's probably the manual stuff
for "challenger" you added to dhcp?
Do you do the ping6 with the same hostname or using the IPv6 address to
make it work again?
Does it make a difference if you try to SSH to the IPv6 address instead of
the hostname?
Usually inter-device connectivity shouldn't be a concern of the router
especially since you have a bridged lan-interface, however there is some
multicast management involved in the bridge-layer.
Could you try to add:
option igmp_snooping 0
into the config interface lan section of /etc/config/network and do a
reboot afterwards and see if it makes any difference?
