Installing and Configuring DHCPv6 2

Overview
How DHCPv6 2.001 Works
Chapter 116
3. Servers respond to the client’s message by sending a RELAY-RELAY
message. The server message is encapsulated in the RELAY-RELAY
message.
4. The relay forwards the server message to the client’s message by
sending ADVERTISE messages.
NOTE All other message interactions are identical to those explained in the
previous scenario.
Identifying and Managing IPv6 Addresses
Servers and clients manage IPv6 addresses in groups called Identity
Associations (IAs). A unique identifier identifies each IA. DHCPv6 2.001
servers allocate IPv6 addresses to clients as IAs. Clients use the
addresses in an IA to configure interfaces. Each address in an IA has its
own preferred and valid lifetimes.
