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.

Perfect House Of Pugs acquired a passion for animals, and the Pug puppy in particular, at a young age since I grew up in a house with lots of dogs. It was a natural ability to know how to grow, nurture, and care for animals. I knew what the future held when I met my wife, who essentially had the same enthusiasm as I have. Being a breeder is more of a passion for me than a profession since I get to witness people's faces light up when they successfully adopt a pug puppy from our facility. It is not possible to find happiness in anything else. PLEASE VISIT OUR WEBSITE LINK BELLOW FOR MORE INFORMATION ABOUT PUG PUPPIES.
