Console#
Address for Multi-segment Network — To generate an IPv6 address that can be
used in a network containing more than one subnet, the switch can be configured
to automatically generate a unique host address based on the local subnet address
prefix received in router advertisement messages, and subsequently from a
DHCPv6 server. (For more information, see the description for the “Restart DHCPv6”
parameter in the System Reference Guide
To dynamically generate an IPv6 host address for the switch, complete the
following steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to access
the interface-configuration mode. Press <Enter>.
2. From the interface prompt, type “ipv6 address autoconfig” and press <Enter>.
3. Type “ipv6 enable” and press <Enter> to enable IPv6 on an interface that has
not been configured with an explicit IPv6 address.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address autoconfig
Console(config-if)#ipv6 enable
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
IPv6 is enabled.
