Nokia SR OS NRS I lab 10 of 14

VPLS

Join three sites into one Ethernet LAN: a full mesh of SDPs, a VPLS with mesh bindings, MAC learning in the FDB, and a table limit.

Run this lab

It needs Standard: its 6 nodes are set to 9 vCPU and 15,936 MB in total.

In your workspace: Shared, then Nokia SR OS NRS I guided labs, then 10 - VPLS

Run it on Standard from £5 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 9 vCPU and 15,936 MB together. Every lab plan includes every guided lab.

The scenario

Birch Logistics has three depots and wants them on one Ethernet LAN, as if every site plugged into the same switch. That's a Virtual Private LAN Service (VPLS). R1, R2 and R3 are the provider edge routers, one per depot. OSPF and LDP are already running, and each router's customer port, 1/1/c3/1, is already an access port. Customer 20 exists.

H1, H2 and H3 are the depots' hosts, on 172.16.20.0/24.

What you’ll practise

  • Explain MAC learning and flooding in a VPLS
  • Build a full mesh of SDPs
  • Build a VPLS with SAPs and mesh SDPs
  • Read and clear the FDB
  • Limit the FDB size

The tasks

  1. Picture the switch
  2. Build the SDPs
  3. Build the VPLS
  4. Watch the FDB fill
  5. Limit the table

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

Topology and devices

The network as it opens in EVE-NG, drawn from the lab’s own canvas, and the image each node runs.

Topology of VPLS6 nodes, 6 links. Every link is listed as text below the diagram.R1R2R3H1H2H3p1/1/3eth0p1/1/3eth0p1/1/3eth0p1/1/2p1/1/1p1/1/2p1/1/2p1/1/1p1/1/1

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder Nokia SR OS NRS I guided labs.

  3. Open 10 - VPLS and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
