Issues and Recommendations with Multiple Stateful DHCPv6 Options
Abstract
The Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
specification defined two stateful options, IA_NA and IA_TA, but did
not anticipate the development of additional stateful options.
DHCPv6 Prefix Delegation added the IA_PD option, which is stateful.
Applications that use IA_NA and IA_PD together have revealed issues
that need to be addressed. This document updates RFCs 3315 and 3633
to address these issues.
