Mmmm... I see no general reasons for this. It came from some non-standard usage of the network stack. > Could you try setting a prefixlen 128 on all aliases except for the > "primary" address (yeah, yeah, I know.. but it helps to talk of a > "primary" address sometimes), and check if the problem persists? No, there is no problem in this case (until you delete the "primary" address"). IPv4 stack also requires the same workaround (primary address + 32bit-masked aliases). Is it by design?
