During that time one IAID Created (ff76fdbd). PxeBcCreateIp6Children()<o:p></o:p> During the Router Advertisement , SARR Process Initiated to get the Boot File. Ip6ConfigInitInstance()<o:p></o:p> <o:p> </o:p> Besides, according to the definition of IA(<a href="https://datatracker.ietf.org/doc/html/rfc3315">RFC-3315</a>):<o:p></o:p> <o:p> </o:p> An "identity-association" (IA) is a construct through which a server and a client can identify, group, and manage a set of related IPv6 addresses. Each IA consists of an IAID and associated configuration information. A client must associate at least one distinct IA with each of its network interfaces for which it is to request the assignment of IPv6 addresses from a DHCP server. The client uses the IAs assigned to an interface to obtain configuration information from a server for that interface. Each IA must be associated with exactly one interface.<o:p></o:p> <o:p> </o:p> But as per EDK2 Network Implementation it defines two IA IDs for same client. Is there any reasoning behind this implementation?<o:p></o:p> <o:p> </o:p> What if both the process uses Same IAID?<o:p></o:p> <o:p> </o:p> Thanks<o:p></o:p> Siva<o:p></o:p> </div> -The information contained in this message may be confidential and proprietary to American Megatrends (AMI).
