-====== Routing with FRR  ======
+===== - Routing with FRR  =====
+The lab environment is based on http://docs.frrouting.org/projects/dev-guide/en/latest/topotests.html. Topotests is a suite of topology tests for FRR built on top of Mininet.
+<code>
+cd /home/user/frr/tests/topotests
+sudo pytest -s --topology-only mooc-lab1/mooc-lab1.py
+</code>
+  * Examples of adding MPLS encapsulation:
+<code>
+on r1
+ip route add 3.3.3.3/32 encap mpls 50000/8300 via 10.0.5.5 dev r1-eth1
+on r3
+ip route add 1.1.1.1/32 encap mpls 50000/8100 via 10.0.3.4 dev r3-eth1
+</code>
+{{::mooc-riv-frr-lab.png?600|}}
+  * `mooc-lab2` implements Segment Routing http://docs.frrouting.org/projects/dev-guide/en/latest/ospf-sr.html.
+What works in the current platform:
+  * IPv4 and IPv6 [tested]
+  * OSPF and BGP [tested]
+  * MPLS and LDP [tested] (with linux kernel, all features are accessible)
+  * Segment Routing! [tested with node-sid et OSPF opaque LSA]
+<WRAP center round tip 60%>
+  * Think about updating FRR to get latest Segment routing features http://docs.frrouting.org/en/latest/pathd.html. PATH is a daemon that handles the installation and deletion of Segment Routing (SR) Policies.

+===== - Docker Containers  =====
+Update the apt package index and install packages to allow apt to use a repository over HTTPS:
+<code>
+$ sudo apt-get update
+$ sudo apt-get install \
+    apt-transport-https \
+    ca-certificates \
+    gnupg \
+    lsb-release
+</code>
+Add Docker’s official GPG key:
+<code>
+$ wget https://download.docker.com/linux/ubuntu/gpg -O key.txt
+$ sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg key.txt
+</code>
+Use the following command to set up the stable repository
+<code>
+echo \
+  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
+  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+</code>
+In order to solve the ''containered.io'' dependency problem, add the following line to the source file ''/etc/apt/sources.list'':
+<code>
+deb http://security.ubuntu.com/ubuntu xenial-security main
+</code>
+Update and install.
+<code>
+$ sudo apt-get update
+$ sudo apt-get install containerd.io
+$ sudo apt-get install docker-ce docker-ce-cli
+</code>
