Hello everyone,<br>
<br>
I'm currently trying to move my OpenVPN users from TAP devices to
TUN devices because Apple states that they will disable TAP in the
near future.<br>
I have it working for IPv4 just fine, but IPv6 gives me a little
OSPF6 issue. The tun0 interface has the following state, even when
people are connected:<br>
<br>
tun0 is up, type POINTOPOINT<br>
Interface ID: 42<br>
Internet Address:<br>
inet : 172.31.8.1/32<br>
inet6: 2a02:b70:0:2::1/64<br>
Instance ID 0, Interface MTU 1500 (autodetect: 1500)<br>
MTU mismatch detection: disabled<br>
Area ID 0.0.0.0, Cost 10<br>
State Down, Transmit Delay 1 sec, Priority 1<br>
Timer intervals configured:<br>
Hello 10, Dead 40, Retransmit 5<br>
DR: 0.0.0.0 BDR: 0.0.0.0<br>
Number of I/F scoped LSAs is 0<br>
0 Pending LSAs for LSUpdate in Time 00:00:00 [thread off]<br>
0 Pending LSAs for LSAck in Time 00:00:00 [thread off]<br>
<br>
I think the "State Down" is the root cause for the routes to this
interface not showing up on other routers, which results in IPv6
traffic failing completely.<br>
Could someone tell me if this is intentionally, or that I have some
potential config error?<br>
If I need to share my whole configuration, let me know, my hope is
that it is something simple related to TUN interfaces / POINTTOPOINT
interfaces.<br>
<br>

interface tun0<br>
ipv6 address 2a02:b70:0:2::1/64<br>
