Lab Notes for RIV MOOC

ONOS and mininet are the most stable solution for testing SDN in the Lab VM.

• Installing ONOS via docker is straighforward

sudo apt-get update
sudo apt-get install     apt-transport-https     ca-certificates    gnupg-agent     software-properties-common
wget https://download.docker.com/linux/ubuntu/gpg
apt-key add gpg
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository    "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"
apt update
sudo apt-get install docker-ce docker-ce-cli containerd.io
docker pull onosproject/onos

• Start mininet (only OpenFlow10 seems to work)

sudo mn --topo tree,2 --mac --switch ovsk,protocols=OpenFlow10 --controller remote,ip=172.17.0.2

• Start ONOS as specified in https://wiki.onosproject.org/display/ONOS/Single+Instance+Docker+deployment and make sure to activate the following apps:

*   8 org.onosproject.drivers              2.4.0.SNAPSHOT Default Drivers
*  26 org.onosproject.optical-model        2.4.0.SNAPSHOT Optical Network Model
*  27 org.onosproject.openflow-base        2.4.0.SNAPSHOT OpenFlow Base Provider
*  57 org.onosproject.netcfghostprovider   2.4.0.SNAPSHOT Network Config Host Provider
*  60 org.onosproject.lldpprovider         2.4.0.SNAPSHOT LLDP Link Provider
*  61 org.onosproject.hostprovider         2.4.0.SNAPSHOT Host Location Provider
*  75 org.onosproject.openflow             2.4.0.SNAPSHOT OpenFlow Provider Suite
* 107 org.onosproject.gui2                 2.4.0.SNAPSHOT ONOS GUI2
* 136 org.onosproject.proxyarp             2.4.0.SNAPSHOT Proxy ARP/NDP
* 158 org.onosproject.fwd                  2.4.0.SNAPSHOT Reactive Forwarding

• For example use: (password karaf)

docker run -t -d -p 8181:8181 -p 8101:8101 -p 5005:5005 -p 830:830 --name onos onosproject/onos
docker exec -it onos /bin/bash
apt update
apt install openssh-server
ssh -p 8101 -o StrictHostKeyChecking=no karaf@localhost

• Check the GUI (login: onos, password: rocks) at http://172.17.0.2:8181/onos/ui/#/topo2
• Activate reactive forwarding:

app activate org.onosproject.fwd

• Or play with intents https://wiki.onosproject.org/display/ONOS/Basic+ONOS+Tutorial:

add-host-intent 00:00:00:00:00:01/None 00:00:00:00:00:04/None

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.

cd /home/user/frr/tests/topotests
sudo pytest -s --topology-only mooc-lab1/mooc-lab1.py

• Examples of adding MPLS encapsulation:

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

• `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]

Update the apt package index and install packages to allow apt to use a repository over HTTPS:

$ sudo apt-get update

$ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    gnupg \
    lsb-release

Add Docker’s official GPG key:

$ wget https://download.docker.com/linux/ubuntu/gpg -O key.txt
$ sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg key.txt

Use the following command to set up the stable repository

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

In order to solve the containered.io dependency problem, add the following line to the source file /etc/apt/sources.list:

deb http://security.ubuntu.com/ubuntu xenial-security main 

Update and install.

$ sudo apt-get update
$ sudo apt-get install containerd.io
$ sudo apt-get install docker-ce docker-ce-cli
