Hi Ivan,
I moved your callback up a little. Also, I see that your have both IPv6 and
IPv4 enabled. I will recommend disabling IPv4 in your lwipopts.h file
temporarily (by #define LWIP_IPV4 0) and see if you can get IPv6 to run by
itself first. Once you get that working, then you can consider running the dual
stack.

Hi Edman,
thanks for the info. I use the STM32 cellular PPP client.
It looks like the example code you have, but does a little bit more. I also add
some logs to trace the Router Advertisemen and nd6_send_rs.
But only IPV6 LL address received.
Really appreciate your help. thanks a lot.

Seems strange though. Because I am using LWIP 2.1.2 and everything is working.
Did you register a callback function as follows during your initialization?:
ppp_set_netif_statuscallback()
ppp_set_netif_linkcallback()
your netif_statuscallback should be triggered once the Router Advertisement
comes in After the solicitation. That’s where you will see your full IPv6
address.
After your pppObject = pppos_create() is successful, you need to do something
like this…
ppp_set_netif_statuscallback(pppObject, pppNetifStatusCB);
Your callback should look something like this
static void pppNetifStatusCB (struct netif *netif)
{
#if LWIP_IPV6
uint8_t i;
#endif
printf("\r\nCELL_PPP: PPP NETIF interface %s\r\n", netif_is_up(netif) ? "UP"
: "DOWN");
#if LWIP_IPV6
// We've been notified that a change is about to take place on the
interface.
// Check if we now have a routable address instead of Link-local address
only.
for (i = 0; i < LWIP_IPV6_NUM_ADDRESSES; i++)
{
if (!ip_addr_isany(netif_ip_addr6(netif, i)) &&
!ip_addr_islinklocal(netif_ip_addr6(netif, i)) )
{
Printf( " Unicast IPv6 Address: %s\r\n",
ip6addr_ntoa(netif_ip6_addr(netif, i)));
}
}
#endif
}
Your can send me snippet of what you are doing if you still have problem. I
have tested this on both BG95 and BG96.

That is the same place I added, but I don't see ipv6 address get through yet.

May I know anything missing?

Hi Ivan,
When you get your callback indicating that the connection is up, that is when
you need to send the router solicitation.
See the example code below in the following link :
https://github.com/particle-iot/lwip-contrib/blob/master/examples/ppp/pppos_example.c
Look at line 96 – 98
#if PPP_IPV6_SUPPORT
fprintf(stderr, " our6_ipaddr = %s\n\r",
ip6addr_ntoa(netif_ip6_addr(pppif, 0)));
This is where you send Router Solicitation
#endif /* PPP_IPV6_SUPPORT */

Hi Edman,
Thanks a lot for the information. It appears that is the same issue I faced.
I tried your suggestion, to add nd6_send_rs, but nothing happened, or I just
add it in wrong place(I call it in ppposif.c).
Could you please shed some light on how to send this rs?
Upgrading to 2.1.3 may not be an option for me for now.
thanks a lot

Hi Ivan,
You need to explicitly send a router solicitation to the network in other to
get the full IPv6 Address. The function to call is nd6_send_rs() in n6.c .
However, this is a static function and you may have to create a wrapper to call
it. As of yesterday, LWIP 2.1.3 was released and they now send RS automatically
for IPv6. Hope this helps as I had the same issue 9 months ago.

Subject: [EXTERNAL] [lwip-users] lwip IPV6 PPP only get link local address and
cannot connect to server
Hi everyone,
I have a project that is running LwIP V2.1.2. The stack is LwIP on top of BG96
cellular modem.
It works fine for IPV4, but when I enable IPV6, I only get IPV6 link local
address, and cannot get real IPV6 address, therefore, I cannot connect to my
server.
The LwIP comes from ST cellular expansion package.
I enable the log, and it got local and remote LL address, but after that never
got any real address, and cannot connect to my server.
thanks a lot for any hints or suggestions.
thanks
Ivan

Notify phase callback, enabled using the PPP_NOTIFY_PHASE config option, let

Notify phase callback can be used, for example, to set a LED pattern depending
