Cisco NX-OS data centre lab 2 of 15

OSPFv2 and OSPFv3 on NX-OS

Bring a Nexus switch into a two-area routed design: interface-based OSPFv2, a stub area with a summary, a passive server VLAN, then OSPFv3 beside it. Then follow one packet from the routing table down to the forwarding table.

Run this lab

It needs Lite: its 4 nodes are set to 5 vCPU and 7,680 MB in total. That fits the free demo too.

In your workspace: Shared, then Cisco Nexus NX-OS data centre guided labs, then 02 - OSPFv2 and OSPFv3 on NX-OS

The scenario

Ashgrove Colocation is fitting out hall 3. You look after its first Nexus switch, N1. R1 is the hall's edge router in area 0, and R2 sits in a new stub area 10 that carries the 10.60.0.0/16 storage networks. R1 and R2 are already configured. N1 has only its name and login. Your job is to route all of it.

What you’ll practise

  • Enable OSPF the NX-OS way: a feature, a named process and interface commands
  • Build an area border router with a stub area and a summary route
  • Run OSPFv3 next to OSPFv2 on the same links
  • Match the reference bandwidth across vendors
  • Compare the RIB, the FIB and the adjacency table for one destination

The tasks

  1. Start the lab
  2. Features and interfaces
  3. OSPFv2 in area 0
  4. A stub area with a summary
  5. Reference bandwidth
  6. OSPFv3 beside OSPFv2
  7. Follow one packet

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

How to open this lab

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

  2. In File Manager, open Shared, then the folder Cisco Nexus NX-OS data centre guided labs.

  3. Open 02 - OSPFv2 and OSPFv3 on NX-OS 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.
