Why AnyIP feature does'nt seem to be working on my ubuntu machine?

I have an ubuntu VPS with a /64 ipv6 subnet assigned to it from the provider. When I connect to the fresh server the networking daemon configuration is: /etc/network/interfaces:

# Generated by SolusVM

 auto lo
  iface lo inet loopback

  auto eth0
  iface eth0 inet static
   address 1xx.yy5.2zz.15
   gateway 1xx.1yy.2zz.1
   netmask 255.255.255.0
   dns-nameservers 1.1.1.1 8.8.8.8
   up ip addr add 2a0c:xyzx:xyzx:xyzx::497e/64 dev eth0
   up ip -6 route add 2a0c:xyzx:xyzx:0000:0000:0000:0000:0001 dev eth0
   up ip -6 route add default via 2a0c:xyzx:xyzx:0000:0000:0000:0000:0001

Now my server responds to ping6 packets that are coming from remote machines addressed to 2a0c:xyzx:xyzx:xyzx::497e. Good. But I want to activate AnyIP feature of linux (as described here) and make my machin respond to ping6 packets sent to any ip from 2a0c:xyzx:xyzx:xyzx::/64 subnet. I assume this should be done by adding the folowing route to the loob back interface. So I inserted this command:

ip -6 route add local 2a0c:xyzx:xyzx:xyzx::/64 dev lo

After adding this route I can do pings of any IP from the subnet locally (from inside my own Ubuntu machine) but my machine still does not respond to remote ping packets addressed to my ipv6 subnet. It only responds to the single IP assigned explicitly to eth0.

Please guide me on how I can make my machine responsible for the whole ipv6 subnet.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
