Similar to my test lab for OSPFv2, I am testing OSPFv3 for IPv6 with the following devices: Cisco ASA, Cisco Router, Fortinet FortiGate, Juniper SSG, Palo Alto, and Quagga Router. I am showing my lab network diagram and the configuration commands/screenshots for all devices. Furthermore, I am listing some basic troubleshooting commands. In the last section, I provide a Tcpdump/Wireshark capture of an initial OSPFv3 run.
I am not going into deep details of OSPFv3 at all. But this lab should give basic hints/examples for configuring OSPFv3 for all of the listed devices.

While reading the OSPF chapter in the Cisco CCNP ROUTE learning guide, I was interested in how to visualize an OSPF area. Since every router in the same area has a complete view of all routers and networks, it should be easy to draw a map. So, I searched through the web for this kind of OSPF plotter and found two different approaches. While none of them worked out of the box, I was able to run one of them with an additional software router (Quagga) inside my OSPF area which finally drew a map. Yeah. Here we go:
