A manually configured global unicast address takes precedence over an automatically generated one.
If a global unicast address has been automatically generated on an interface when you manually
configure another one with the same address prefix, the latter overwrites the previous. The overwritten
automatic global unicast address is not restored even if the manual one is removed. Instead, a new
global unicast address is automatically generated based on the address prefix information in the RA
message that the interface receives at the next time.
EUI-64 IPv6 addressing
To configure an interface to generate an EUI-64 IPv6 address:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the interface to
generate an EUI-64 IPv6
address.
ipv6 address
ipv6-address/prefix-length eui-64
By default, no IPv6 global unicast
address is configured on an interface.
Manual configuration
To specify an IPv6 address manually for an interface:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure an IPv6 address
manually.
ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
By default, no IPv6 global unicast
address is configured on an interface.
Stateless address autoconfiguration
To configure an interface to generate an IPv6 address by using stateless address autoconfiguration:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure an IPv6 address to
be generated through
stateless address
autoconfiguration.
ipv6 address auto
By default, no IPv6 global unicast address is
configured on an interface.
Using the undo ipv6 address auto command
on an interface removes all IPv6 global
unicast addresses automatically generated
on the interface.
Applying a prefix to generate an IPv6 address
Before you apply a prefix to an interface to generate an IPv6 address, create an IPv6 prefix with one of
the following methods:
