[gauravd]

First check the connection and IP address:

#ip addr
#nmcli connection show

Then add IPv6 address on default connection:

#nmcli connection modify eth0 [B]ipv6.address 2006:ac81::1105/64[/B]
#nmcli connection modify eth0 ipv6.method manual

Then, active the connection:

#nmcli connection up systemeth0
#nmcli connection reload

Check IPv6 address is correctly added on the device:

#nmcli connection show eth0 | grep ipv6

Enable ONBOOT option:

#nmcli connection modify eth0 connection.autoconnect yes

Finally ping to the IPv6 Address:

#ping 2006:ac18::1105
