Linux CentOS 7 - Configuring IPv6 addresses

Configure an IPv6 address for an ethernet type interface.

On system1

Make sure the NetworkManager process is up and running.
# systemctl status NetworkManager
# nmcli con mod ens33 ipv6.addresses 2001:abcd:abcd::1/64 autoconnect yes ipv6.method static

Restart the network process
# systemctl restart network

Verify the interface has the right address
# ip a

Verify the IPv6 address can be pinged
# ping6 2001:abcd:abcd::1

On system2

Repeat the steps above with the address 2001:abcd:abcd::2/64.

Verify the interfaces can ping one another.

If you experience any problem with this configuration, please let me know.
