The client's source address selection #4

Closed frozensunq closed 10 years ago

The client's source address needs to be of the same or 'wider' scope than the destination address because the client may be instructed to use a unicast address; otherwise, the responses may not make it back. This is different than the RFC 3315 text which says to use the link-local source address.

Add a paragraph in the section of 4o6 DHCP Client Behavior: The 4o6 DHCP client MUST employ a source IPv6 address of a proper scope to send the DHCPv4-query message. When the client sends a DHCPv4-query message to the multicast address, it MUST use a link-local address as the source address as in RFC3315. When the client sends a DHCPv4-query message using unicast, the source address MUST be the global IPv6 address acquired in advance.
