In the nets folder there are different projects:

- 3routers
small IPv4 topology with OSPF / FRR

- 8routers
reference IPv6 topology with OSPFv3 / FRR

- 8routers-isis-ipv6
reference IPv6 topology with IS-IS / FRR

- 8r-1c-out-band-isis
reference IPv6 topology with IS-IS / FRR and out-of-band controller

- 8r-1c-in-band-isis

You need to have FRR installed in order to run the mininet labs. Check if FRR is installed by running:

  
  /usr/lib/frr/zebra -v

If FRR is not installed, follow these instructions (for Ubuntu/Debian):

1. wget https://deb.frrouting.org/frr/keys.asc

2. sudo apt-key add keys.asc

3. rm keys.asc

4. run lsb_release -s -c

5. Edit the sources.list file in the /etc/apt folder, adding the following line at the end:

deb https://deb.frrouting.org/frr <release> frr-stable	

replacing with the output of lsb_release -s -c

6. sudo apt update

7. sudo apt -y install frr frr-pythontools
