When I ping another ipv6 address on the same host from the loopback interface, it fails.
Is this what was expected? Or should it work successfully like ipv4?
Reproduction:
root@test:~ # ifconfig ens8
ens8: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 2008::8 prefixlen 128 scopeid 0x0<global>

root@test:~ # ping -c 3 -I ::1 2008::8
