Example2:
When the network operator is deploying IPv6 networks, network automatically configuration
can be achieved through the prefix delegation allocation of IPv6 addresses, in stead of
configuring manually for each switch:
To configure the switching or routing device which is connected to the client switch as DHCPv6
prefix delegation server, that is to setup a local database for the relationship between the
allocated prefix and the DUID of the client switch.
To configure the switch as the prefix delegation client, and make the client switch to get IPv6
address prefix from the prefix delegation server, through a process which is much like the
process of DHCPv6 address allocation.
The edge devices which receive the address prefix, send routing advertisement - RA
messages, to the client hosts about the address prefix through the interface which is
connected to the hosts, then the hosts get an valid IPv6 address through stateless auto
configuration, while at the same time, the stateless DHCPv6 server will be configured for the
interface, in order to provide the DHCPv6 client with information such as DNS, and domain
name, etc.
Network Topology:
The edge switch is a Switch1 switch. The interface connected to the trunk switch which is
