OSPFv3 for IPv6 and IPv4 address families

Route Fernhill's new dual-stack network with OSPFv3 address families: three areas for IPv6, an ABR summary, and IPv4 carried by the same OSPFv3 process.

Run this lab

It needs Lite: its 4 nodes are set to 4 vCPU and 2,048 MB in total. That fits the free demo too.

The scenario

Fernhill Freight is rolling out IPv6 alongside IPv4. The addressing team has finished their part: every interface has an IPv4 address, a global IPv6 address and a readable link-local address (FE80::<router number>). Your task is the routing. The design team wants one routing protocol for both families, so you'll use OSPFv3 with address families: area 0 at head office, area 1 in Bristol and area 2 in Glasgow, with Bristol summarised at its ABR.

Router IDs: R*n* uses n.n.n.n.

Topology: R3 — R1 — R2 — R4 in a line (R1 is the ABR for area 1, R2 for area 2).

What you’ll practise

  • Explain how OSPFv3 differs from OSPFv2: per-link operation, link-local next hops and the new LSA types
  • Configure OSPFv3 with the address-family model for IPv6 across three areas
  • Use point-to-point network types and advertise simulated LANs with their real prefix length
  • Summarise IPv6 and IPv4 prefixes on an OSPFv3 ABR
  • Run the IPv4 address family inside OSPFv3 and verify both families end to end

The tasks

  1. Look at the IPv6 addressing
  2. Start OSPFv3 for IPv6
  3. Make the WAN links point-to-point and the LANs real
  4. Read the OSPFv3 database
  5. Summarise Bristol at its ABR
  6. Carry IPv4 in OSPFv3 too
  7. Test both families end to end

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 CCNP ENCOR 350-401 guided labs.

  3. Open 10 - OSPFv3 for IPv6 and IPv4 address families 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.
