OSPF routing protocol is like a puzzle with the LSAs packets as the pieces that you put together in order to arrive at the correct topology.

The idea behind this scenarios I created is to provide outputs of the show ipv6 ospf database commands of all routers and you are asked to draw the topology.

The goal is to understand what inside the LSAs and how to interpret the body in order to guess successfully the topology and how the routers are interconnected, which prefix is attached to each segment and link, and which type of link is used between two routers. This is a good method to understand the Link State Database LSDB which is a collection of LSAs packet.

The scenario is based on OSPFv3 which is for IPv6 where new LSAs 8 and 9 are added to carry prefix informations. So with more pieces of puzzle to use compared with OSPFv2.
