Enable and configure IPv6 on TAS servers

Enable IPv6 on all TAS servers, and configure the required settings for the network interface used for external communication.

Procedure 

  1. Go to /etc/sysconfig/ and open the network file in an editor:

    Copy
    vi /etc/sysconfig/network

  2. Append the following line to the file:

    NETWORKING_IPV6=yes

  3. Save the file and exit.

  4. Get the list of all available network interfaces:

    Copy
    ls -l /sys/class/net

    Example of output:

    lrwxrwxrwx 1 root root 0 Feb 19 13:00 docker0 -> ../../devices/virtual/net/docker0

    lrwxrwxrwx 1 root root 0 Feb 19 13:44 eth0 -> ../../devices/LNXSYSTM:00/device:00/PNP0A03:00/device:08/VMBUS:01/vmbus_13/net/eth0

    lrwxrwxrwx 1 root root 0 Feb 22 11:39 lo -> ../../devices/virtual/net/lo

    lrwxrwxrwx 1 root root 0 Feb 19 13:00 veth2d8bbd6 -> ../../devices/virtual/net/veth2d8bbd6

    lrwxrwxrwx 1 root root 0 Feb 19 13:00 veth86d633a -> ../../devices/virtual/net/veth86d633a

    lrwxrwxrwx 1 root root 0 Feb 19 13:00 vethe405ef2 -> ../../devices/virtual/net/vethe405ef2

    lrwxrwxrwx 1 root root 0 Feb 19 13:00 virbr0 -> ../../devices/virtual/net/virbr0

    lrwxrwxrwx 1 root root 0 Feb 19 13:00 virbr0-nic -> ../../devices/virtual/net/virbr0-nic

  5. Filter the list of network interfaces to show only those interfaces that are not under devices/virtual.

  6. Go to /etc/sysconfig/network-scripts, and open the configuration file for the network interface in an editor:

    Copy
    vi /etc/sysconfig/network-scripts/ifcfg-<interface_name>

    where:

    <interface_name> is the name of the network interface, for example, eth0.

  7. Make sure the following keys are present and set to yes.

    IPV6INIT=yes

    IPV6_AUTOCONF=yes

  8. Save the file.

  9. Restart the network service:

    Copy 
    systemctl restart network
    systemctl restart NetworkManager
