Sorry for this garbage, I just resend my email :
I spotted a problem with ra_management = 2
First configuration: stateful only configuration/
sbin/route -A inet6
noyauDestination Next Hop Flag Met
Ref Use If2a01:e35:xxxx:xxxx::3/128 :: U
256 0 0 eth0fe80::/64 ::
U 256 1 4 eth0::/0 ::

Un 0 11 101 lo2a01:e35:xxxx:xxxx::3/128
:: Un 0 1 15
lofe80::5642:49ff:xxxx:xxxx/128 :: Un 0 1

There is no unique gateway (no Next Hop for ::/0).
The unique gateway should be the local address of the OpenWRT gateway.
As a result, ping6 does not work (network unreachable).
Second configuration: static IPv6 configuration
If i set the IPv6 staticly with correct gateway, the routing table
becomes:
/sbin/route -A inet6
noyauDestination Next Hop Flag Met
Ref Use If2a01:e35:xxxx:xxxx::7/128 :: U
256 0 0 eth0fe80::ea94:f6ff:xxxx:xxxx/128 ::
U 100 0 3 eth0fe80::/64 ::
U 256 0 0 eth0::/0

0 1 9 loff00::/8 ::
U 256 2 0 eth0::/0 ::
!n -1 1 11937 lo
fe80::ea94:f6ff:xxxx:xxx is the correct UG. ping6 works.
To me, it seems that when using stateful only configuration, IPv6
gateway is not broadcasted. How can this be configured/fixed?
Kind regards,
