There is only one reason it exists: to define an IP address as being link local. This influences what address is used as the src when going on different paths which also have link scope. > It must not exist to cause IPv4 ARP to do broadcast as specified in RFC > 3927, or we would not be having this conversation. > RFC 3927 defines what addresses are legit link local scope. The kernel says what to do with addresses that are link local scopes. It knows this if you tell it is a link local address. > Overloading its current semantics, will cause in unnecessary ARP > broadcasts in non RFC 3927 cases. > Refer to what i said above. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
