Re: [lwip-users] IPV6 Porting

[ffddybz]

Thank you for your reply. I succeed in testing IPV6 via ND6 protocol. But I also want to test it using static IPV6 address, the process of doing this, I created linklocal address, then I use IP6_ADDR macro to add address to struct ip6addr, I use function netif_get_ip6_addr_match to bind struct netif and struct ip6_addr, Then you tell me using macro netif_ip6_addr_set_state. But I can't create IPV6 address, and struct netif did not contain any information about IPV6 address. Am I doing right?

This used to be in one of the LwIP Wikia pages but now it is gone ... 
??

The netif has some placeholders for IPv6 addresses: 
my_netif->ip6_addr[xx]. The number of addresses is configurable in 
lwipopts.h, usually 3 is a good number.

Usually address [0] is reserved for the link-local address. If your 
netif has a hw_addr configured you can use 
netif_create_ip6_linklocal_address() to create the address. You can 
manually create the rest of the adresses, or if you have adress 
auto-configuration enabled you can let the ND6 protocol generate the 
rest of the adresses with help from your IPv6 router. you should set 
netif->ip6_autoconfig_enabled = 1; and make sure it is enabled in 
lwipopts.h

Any address you manually configure, you should use the macro 
netif_ip6_addr_set_state(netif, addr_index, IP6_ADDR_TENTATIVE) to let 
ND6 protocol validate it.

That is all you need to get set up.

If you have any other questions just ask.

Cheers
Ivan
