OSPFv3 address families for IPv4 and IPv6

Run IPv4 and IPv6 in one OSPFv3 process with address families, make the branch area totally stubby for both, summarise each family, authenticate the backbone with IPsec, and read the new OSPFv3 LSA types.

The scenario

Pinecrest Logistics is rolling out IPv6 and wants one routing protocol for both address families. Instead of running OSPFv2 for IPv4 and OSPFv3 for IPv6 side by side, the design uses OSPFv3 with address families: one process, one set of adjacencies per family, one way of working. HQ (R1) and the core router R2 form area 0; the branch (R3) and warehouse (R4) are area 1, which only needs a default route out. The warehouse still has an IPv4-only scanner network that must be reachable.

Topology: a chain, R1 — R2 — R3 — R4. ipv6 unicast-routing is already on; no routing protocol is configured.

What you’ll practise

  • Configure router ospfv3 with IPv6 and IPv4 address families and enable them per interface
  • Explain why the IPv4 address family needs IPv6 enabled on every interface
  • Configure a totally stubby area and inter-area summaries per address family
  • Authenticate OSPFv3 with IPsec (SPI and SHA-1 key)
  • Identify OSPFv3 link (type 8) and intra-area prefix (type 9) LSAs

The tasks

  1. OSPFv3 for IPv6
  2. Add the IPv4 address family
  3. Make area 1 totally stubby for both families
  4. Summarise area 1 in each family
  5. Authenticate the backbone with IPsec
  6. Read the OSPFv3 database
  7. Test both families

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 ENARSI 300-410 guided labs.

  3. Open 08 - OSPFv3 address families for IPv4 and IPv6 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.
