A large network scale leads to a huge LSDB size, causes routers to consume much storage space, affects network performance. To prevent these problems, you can configure OSPFv3 to divide an AS to different areas
In real-world situations, you need to subtly configure the OSPF routing information sometimes to meet the requirements of complex networks, which implements the accurate control on the OSPF routing information.
If an Open Shortest Path First version 3 (OSPFv3) network requires high security, you can configure an authentication mode to improve network security.
