Solving method
This method is based on a simple fact: even IE ignores

Take a look at the following code, an example of a simple acronym:
Now, compare the modified code:
whether the mask is consistent. If the mask is consistent, send the message. If the mask is inconsistent, discard the message directly.If not, the route information is summarized into the corresponding primary network and then sent out. (2) To receive route updates, first confirm whether the received route information is the same as the interface for receiving the information. If yes, use the mask of this interface and write the route to the route table.If not, check whether the primary network
-inherent security. By using the IPv6 protocol package's security sub-header integration system, OSPFv3 messages can be authenticated and encrypted, which previously required independent and complex protocols 。
OSPFv3 provides more powerful functions and has a great deal of versatility, so it can easily support new network protocols. New features simplify network equipment and operations, when OSPFv3 is used, the upgrade will not be so troublesome 。
(2) The difference between IS-ISv6 and IS-ISv4

OSPF lies in minimum cost routing, multiple same path calculation and load balancing. OSPF has two main features of openness and the use of SPF algorithms.
Intermediate System-Intermediate System Protocol (ISIS)
The ISIS protocol is also a routing protocol based on link state. The protocol, proposed by ISO, was initially used in the OSI network environment and later modified to operate in a dual environm
principle: variable name = Attribute + Type + object description ). This naming method is common in C and C ++.
Avoid using identifiers that conflict with keywords in a widely used programming language. Although keywords can be used as identifiers by adding the "@" prefix in C #, it is much more difficult to use escape sequences when using methods. In the Razor Syntax of Asp. Net MVC development mode, the in-row expressions (variables and functions) both start. Therefore, it is not recommended
