[lwip-devel] [bug #30039] AutoIP does not reuse previous addresses

[Simon Goldschmidt]

Follow-up Comment #5, bug #30039 (project lwip):

Shouldn't the parameter 'netif' to LWIP_AUTOIP_CREATE_SEED_ADDR() make it
pretty improbable that 2 netifs decide to try the same address? And if so,
what would be the problem? If you were to send from an application program to
an AutoIP address with more than one AutoIP netif, no matter if the 2 netifs
have the same address or not, the order of the list would decide about the
target network.

After all, AutoIP addresses should be link-local. As long as your 2 netifs
aren't connected to the same link, they may even have the same address.

> Whoops - autoip_start in previous post where I used dhcp_start...
Yes, it didn't make much sense without that change :-)
