Experiment with real-time network telemetry using containerlab to simulate Clos (leaf/spine) fabrics.
- Real-time telemetry from a 5 stage Clos fabric
- Topology aware fabric analytics
- Real-time EVPN fabric visibility
- Containerlab DDoS testbed
- DDoS attacks and BGP Flowspec responses
- BGP Remotely Triggered Blackhole (RTBH)
- SR Linux in Containerlab
- Real-time flow analytics with Containerlab templates
- Leaf and spine network emulation on Mac OS M1/M2 systems
- Containerlab dashboard
- Emulating congestion with Containerlab
- AI network performance monitoring using containerlab
Get started (on a system running Docker):
git clone https://github.com/sflow-rt/containerlab.git
cd containerlab
./run-clab
Deploy 5 stage Clos topology:
containerlab deploy -t clos5.yml
Upload topology to sFlow-RT:
./topo.py clab-clos5
Generate traffic between h1 and h4:
docker exec -it clab-clos5-h1 iperf3 -c 172.16.4.2
docker exec -it clab-clos5-h1 iperf3 -c 2001:172:16:4::2
Connect to http://localhost:8008/ for analytics, see Quickstart for more information.
Deploy 3 stage Clos topology:
containerlab deploy -t clos3.yml
Upload topology to sFlow-RT:
./topo.py clab-clos3
Generate traffic between h1 and h2:
docker exec -it clab-clos3-h1 iperf3 -c 172.16.2.2
docker exec -it clab-clos3-h1 iperf3 -c 2001:172:16:2::2
Connect to http://localhost:8008/ for analytics, see Quickstart for more information.
Deploy EVPN topology:
containerlab deploy -t evpn3.yml
Upload topology to sFlow-RT:
./topo.py clab-evpn3
Generate traffic between h1 and h2:
docker exec -it clab-evpn3-h1 iperf3 -c 172.16.10.2
docker exec -it clab-evpn3-h1 iperf3 -c 2001:172:16:10::2
Connect to http://localhost:8008/ for analytics, see Quickstart for more information.
Deploy RoCEv2 toplogy:
containerlab deploy -t rocev2.yml
Upload topology to sFlow-RT:
./topo.py clab-rocev2
Generate traffic between h1 and h2:
docker exec -it clab-rocev2-h1 hping3 exec rocev2.tcl 172.16.2.2 10000 500 100
Connect to http://localhost:8008/ for analytics, see Quickstart for more information.
Deploy DDOS topology:
containerlab deploy -t ddos.yml
Simulate DDoS attack against victim:
docker exec -it clab-ddos-attacker hping3 --flood --udp -k -a 198.51.100.1 -s 53 192.0.2.129
Connect to http://localhost:8008/ for analytics, see Quickstart for more information.
Deploy SR Linux topology:
containerlab deploy -t srlinux.yml
Simulate traffic:
docker exec -it clab-srlinux-h1 iperf3 -c 172.16.2.2
