Usage guidelines
The temporary address feature enables the system to generate and preferentially use the temporary
IPv6 address of the sending interface as the source address of a packet. If the temporary IPv6
address cannot be used because of a DAD conflict, the system uses the public IPv6 address.
Examples
# Enable the system to preferentially use the temporary IPv6 address of the sending interface as the
source address of the packet.
<Sysname> system-view
[Sysname] ipv6 prefer temporary-address
