	English We can then manually configure the IPv6 addresses of each host/router on each link. Let us start with the links attached to the two hosts. 138/10000 · 138
70 ../../exercises/ipv6.rst:631

	English The same can be done for the three links between the different routers. 71/10000 · 71
71 ../../exercises/ipv6.rst:648

	English With these IP prefixes and the network topology, we can now use IPMininet_ to create the topology and assign the addresses. 123/10000 · 123
72 ../../exercises/ipv6.rst:656

	English We start by creating the objects that correspond to the static routes on the three routers. The second argument of the ``addDaemon`` method is a list of ``StaticRoute`` objects. Each of these objects is created by specifying an IP prefix and a nexthop. 252/10000 · 252
73 ../../exercises/ipv6.rst:675

	English We can now create the hosts and the routers 43/10000 · 43

	English With this ``build`` method, we can now launch the network by using the python code below. 89/10000 · 89

	English To help students to start using IPMininet, `Mathieu Jadin <https://inl.info.ucl.ac.be/mjadin.html>`_ has created a Vagrant box that launches a Ubuntu virtual machine with all the required software. See https://ipmininet.readthedocs.io/en/latest/install.html for additional information. 285/10000 · 285
77 ../../exercises/ipv6.rst:698

	English Here is a simple example of the utilization of this Vagrant box. 64/10000 · 64

	English We start the network topology shown above with the ``sudo python script.py`` command. It launches the mininet_ interactive shell that provides several useful commands: 167/10000 · 167
79 ../../exercises/ipv6.rst:732

	English Some of the standard mininet commands assume the utilisation of IPv4 and do not have a direct IPv6 equivalent. Here are some useful commands. 141/10000 · 141
80 ../../exercises/ipv6.rst:734

	English The ``nodes`` command lists the routers and hosts that have been created in the mininet topology. 97/10000 · 97
81 ../../exercises/ipv6.rst:743

	English The ``links`` command lists the links that have been instantiated and shows that mapping between the named interfaces on each node. 131/10000 · 131
82 ../../exercises/ipv6.rst:760

	English It is possible to execute any of the standard Linux commands to configure the network stack on any of the hosts by prefixing the command with the corresponding host. Remember to always specify ``inet6`` as the address family to retrieve the IPv6 information. 258/10000 · 258
83 ../../exercises/ipv6.rst:770

	English Host ``a`` has two interfaces: the standard loopback interface and a network interface named ``a-eth0`` that is attached to router ``r1``. We can also verify how the IPv6 addresses have been configured: 202/10000 · 202
