Nokia SR OS NRS I lab 9 of 14

Epipe (VPWS)

Join two customer sites with a point-to-point Layer 2 service: access ports, a customer, an SDP over LDP, an Epipe, and OAM tests of each layer.

Run this lab

It needs Standard: its 4 nodes are set to 6 vCPU and 10,624 MB in total.

In your workspace: Shared, then Nokia SR OS NRS I guided labs, then 09 - Epipe - VPWS

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 6 vCPU and 10,624 MB together. Every lab plan includes every guided lab.

The scenario

Alder Foods has a site at Ashby and a site at Brenton, and it wants them joined by what looks like a single Ethernet cable. It runs its own IP addressing, and Rivermark shouldn't need to know anything about it. That's a point-to-point Layer 2 service, a Virtual Private Wire Service (VPWS), which SR OS calls an Epipe.

H1 and H2 are the customer's hosts, on 172.16.10.0/24. OSPF and LDP already run between R1 and R2, so an MPLS tunnel exists. Everything else is your job.

What you’ll practise

  • Name the parts of the SR OS service model
  • Change a port to access mode
  • Build an MPLS SDP over LDP
  • Build an Epipe with a SAP and a spoke SDP
  • Test tunnels and pseudowires with OAM

The tasks

  1. Learn the service model
  2. Turn the customer port into an access port
  3. Build the SDP
  4. Build the Epipe
  5. Test the service, not just the hosts
  6. See a service in the MD-CLI

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 Epipe - VPWS4 nodes, 3 links. Every link is listed as text below the diagram.R1R2H1H2p1/1/2eth0p1/1/2eth0p1/1/1p1/1/1
4 nodes, with the interface names each link uses. On a narrow screen, scroll the diagram sideways.

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 09 - Epipe - VPWS 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.
