IPv6 topology discovery

Topology discovery tool supporting IPv6 in vyos1.3
Router discovery
^^^^^^^^^^^^^^^^
Vyos 1.3 supports the following commands to complete IPv6 Router Discovery:
.. code-block:: none
vyos@vyos:~$ force ipv6-rd interface <interface> address <ip>
Example:
.. code-block:: none
vyos@vyos:~$ force ipv6-rd interface <interface> address <ip>

Neighbor Discovery
^^^^^^^^^^^^^^^^^^
Vyos1.3 supports IPv6 host topology detection. The following commands can be used to detect the occupation of IPv6 address:
.. code-block:: none
vyos@vyos:~$ force ipv6-nd interface <interface> address <ip>
Example:
.. code-block:: none
vyos@vyos:~$ force ipv6-nd interface eth0 address fc00:470:f1cd:101::1
