[lwip-devel] [lwIP 2.0.3] IPV6 ND6 issue

[Omar SAEED]

Hello,

I'm using LWIP Stack with both IPV4 and IPV6 enabled,

The initialization flow is as below 

• xemac_add
  
• netif_add
  
• xaxiemacif_init
  
• ethip6_output
  
• nd6_get_next_hop_addr_or_queue
• nd6_get_next_hop_entry

This last function nd6_get_next_hop_entry

calling the function nd6_get_next_hop_entry() is returning (Routing problem i.e. ERR_RTE) because the IP is not a linklocal IP and netif is not prefixed as a neighbor, So the function goes to selecting a router at the other "else" branch, 

The function nd6_select_router() contain the comment (must implement ND6_OPTION_TYPE_ROUTE_INFO), 

Can any one support at this point, I don't know really what is needed and if there is some #define need to be activated at "opt.h" or if there is a patch at the forum that I need to get.

Thanks for your time
