Switch2(Config-if-Vlan100)#exit
Switch2(config)#
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:
1. 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.
2. 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.
3. 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
Switch2, is configured as the prefix delegation client. The interfaces connected to hosts, are
configured as stateless DHCPv6 servers to provide the hosts with stateless information such
as DNS and domain names, also routing advertisement of stateless address allocation is
enabled for the host interfaces; On Switch2, the prefix delegation server is configured, and
routing advertisement of state address allocation is enabled; On the host side, DHCPv6 client
capable operating system such Windows Vista should be installed.
