v::n osvbng

Description#

This lab demonstrates a minimal BNG (Broadband Network Gateway) topology using v::n osvbng for subscriber termination, BNG Blaster as a subscriber traffic simulator, and FRR as the core router.

The topology simulates a real-world broadband access network with QinQ IPoE subscriber sessions using DHCPv4 and DHCPv6.

subscribers:eth1 <----> bng1:eth1 (access)
                        bng1:eth2 (core) <----> corerouter1:eth1

• subscribers - BNG Blaster container simulating subscribers with Q-in-Q tagged IPoE sessions over DHCPv4/DHCPv6
• bng1 - osvbng node performing subscriber termination with OSPF/OSPFv3 towards the core
• corerouter1 - FRR router acting as the core/upstream router

Deployment#

Deploy the lab:

sudo containerlab deploy -t osvbng01.clab.yml

Wait a few seconds for osvbng to boot and establish OSPF adjacency, then verify:

docker exec clab-osvbng01-corerouter1 vtysh -c "show ip ospf neighbor"

You should see bng1 as a Full neighbor.

Running BNG Blaster#

Start BNG Blaster to simulate subscriber sessions:

docker exec -it clab-osvbng01-subscribers bngblaster -C /config/config.json

BNG Blaster will establish IPoE sessions with DHCPv4 and DHCPv6 and report session status:

Sessions PPPoE: 0 IPoE: 1
Sessions established: 1/1
DHCPv6 sessions established: 1

Cleanup#

Destroy the lab:

sudo containerlab destroy -t osvbng01.clab.yml
