Prevent an IPv6 address on an interface from being used as source address of packets.

ip addr change 2001:db8:1:2::ab dev eth0 preferred_lft 0
If two or more IPv6 addresses are assigned to an interface, apply this command to all but the address that you want to use as the source address of outbound packets. This is Linux-specific and requires the iproute package, or equivalent for your distribution.
