[Sysname] interface Vlan-interface 1
[Sysname-Vlan-interface1] ipv6 address auto link-local
ipv6 address eui-64
Syntax
ipv6 address ipv6-address/prefix-length eui-64
undo ipv6 address ipv6-address/prefix-length eui-64
View
VLAN interface view
Parameters
ipv6-address/prefix-length: IPv6 address and IPv6 prefix. The ipv6-address and prefix-length
arguments jointly specify the prefix of an IPv6 address in the EUI-64 format. The prefix length of an
EUI-64 address cannot be greater than 64.
Description
Use the ipv6 address eui-64 command to configure a site-local address or global unicast address in
the EUI-64 format for an interface.
Use the undo ipv6 address eui-64 command to remove the configured site-local address or global
unicast address in the EUI-64 format for an interface.
By default, no site-local address or global unicast address in the EUI-64 format is configured on the
interface.
An IPv6 address in the EUI-64 format consists of a specific prefix and the MAC address of the local
device, which can be displayed using the display ipv6 interface command.
Note that:
The prefix length should not be more than 64 bits when a aggregatable global unicast address(es) or
site-local address(es) in the EUI-64 format is configured.
Examples
# Configure an IPv6 address in the EUI-64 format for the VLAN-interface 1. The prefix of the address is
2001::1/64, and the interface ID is generated based on the MAC address of the device.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] interface Vlan-interface 1
[Sysname-Vlan-interface1] ipv6 address 2001::1/64 eui-64
# Display the generated IPv6 address in the EUI-64 format.
