To con?¬?gure an IPv6 address for an interface and enable IPv6 processing on the interface
using an EUI-64 interface ID in the low order 64 bits of the address (host), use the ipv6
address ipv6-pre?¬?x/pre?¬?x-length eui-64 command in interface con?¬?guration mode.
To assign the IPv6 address 2001:0DB8:0:1::/64 to Ethernet interface 0 and use an EUI-64
interface ID in the low order 64 bits of the address, enter the following commands:
RouterX(config)# iinntteerrffaaccee eetthheerrnneett 00
RouterX(config-if)# iippvv66 aaddddrreessss 22000011::00DDBB88::00::11:::://6644 eeuuii--6644
Stateless Autoconfiguration
As the name implies, autocon?¬?guration is a mechanism that automatically con?¬?gures the
IPv6 address of a node. In IPv6, it is assumed that non-PC devices, as well as computer
terminals, will be connected to the network. The autocon?¬?guration mechanism was
introduced to enable plug-and-play networking of these devices, to help reduce
administration overhead.
DHCPv6 (Stateful)
DHCP for IPv6 enables DHCP servers to pass con?¬?guration parameters such as IPv6
network addresses to IPv6 nodes. It offers the capability of automatic allocation of reusable
network addresses and additional con?¬?guration ?¬‚exibility.
