OSPFv3 is an interior gateway routing protocol,
which is widely used in IPV6 environment. It is the realization
of OSPFv2 for IPV4 in the IPV6 environment. They are the
same in the basic principles. The paper uses the OPNET
network simulation software to simulate and analyze the
performance of OSPFv3, and found that both the convergence
period is the same roughly, the flow is concentrated in the first
few seconds. But they also have many different aspects, a
change in the packet format, and the type of LSA. There is no
address information in OSPFv3 and the main LSAs. Router
LSA is only 83% of OSPFv2. Router ID does not have any
practical significance. Although IPV6 address is 4 times the
IPV4 address, both are the same roughly in the memory and
running time. And there are many improvements. (Abstract)
