Nokia SR OS NRS I lab 11 of 14

VPRN and IES

Build two Layer 3 VPNs with the same addresses over MP-BGP and LDP, then give a third customer a routed IES in the global table.

Run this lab

It needs Standard: its 7 nodes are set to 9 vCPU and 12,160 MB in total.

In your workspace: Shared, then Nokia SR OS NRS I guided labs, then 11 - VPRN and IES

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 12,160 MB together. Every lab plan includes every guided lab.

The scenario

Rivermark now sells Layer 3 services. Two customers want private IP networks between their Ashby and Brenton offices: Alder Foods and Cedar Mutual. Both picked the same addressing, 172.16.1.0/24 and 172.16.2.0/24, and neither will change. A third customer, Dunmere Cafe, just wants a routed connection in Rivermark's own global table.

That's two VPRNs and an IES. OSPF and LDP already run between R1 and R2, the customer ports are access ports, and customers 30, 31 and 32 exist.

What you’ll practise

  • Explain route distinguishers, route targets and MP-BGP
  • Bring up a vpn-ipv4 BGP session
  • Build VPRNs with interfaces on SAPs
  • Keep overlapping customers apart
  • Build an IES and add it to the IGP

The tasks

  1. Understand a VPRN
  2. Bring up MP-BGP
  3. Build Alder's VPRN
  4. Build Cedar's VPRN with the same addresses
  5. Add an IES for Dunmere

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 VPRN and IES7 nodes, 6 links. Every link is listed as text below the diagram.R1R2A1B1I1A2B2p1/1/3eth0p1/1/3eth0p1/1/2eth0p1/1/4eth0p1/1/2eth0p1/1/1p1/1/1

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 11 - VPRN and IES 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.
