Currently, there are many kinds of router protocols. Today, I will explain the RIP, HELLO, and EGP technologies in the vro protocol. I will share them with you here, hoping they will be useful to you. Technically, the IGP Router Protocol is similar to RIP and HELLO. The router uses this vro protocol to obtain information about other vrouters in the autonomous system to update its route table. Unlike the internal Router Protocol, EGP also performs othe
Currently, the vro protocol is widely used. Many people may not know the RIP, HELLO, and egp in the vro protocol. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. Technically, the IGP protocol is the same as RIP and HELLO protocol. Vro uses this Protocol to obtain information about other vro protocols in the autonomous system so as to update its routing table. Unlik

Oracle DatabaseOfAutonomous transactionsThis is what we will introduce in this article. Next let's take a look at its mysteries.
A database transaction is a unit operation. Either all operations are successful or all operations fail. In Oracle, a transaction starts from the execution of the first data management language DML) statement until a COMMIT statement is executed, the transaction is committed and saved, or a ROLLBACK statement is executed, stop this operation.

I. OSPF Routing Protocol
1) Introduction to OSPF Routing Protocol
OSPF is the abbreviation of "Open Shortest Path First. It is a link-based autonomous system internal routing protocol developed by IETF. On an IP network, it dynamically discovers and transmits routes by collecting and passing the link status of the
through various networks, causing routers to restart their routing algorithms and update their route tables to dynamically reflect network topology changes. The Dynamic Routing Protocol is applicable to networks with large networks and complex network topologies. Of course, various dynamic routing protocols occupy network bandwidth and CPU resources to varying degrees.
Static Routing and dynamic routing protocols have their own characteristics and applicability. Therefore, dynamic routing is us

The routing protocol used in the autonomous region is called the internal gateway protocol, which is commonly used with RIP and OSPF. The external gateway protocol i

, the route selection software will recalculate the route, new route update information is sent concurrently. This information is transmitted through each network, causing Each router to restart its routing algorithm, and update their route tables to dynamically reflect network topology changes.

Of course, various dynamic routing protocols occupy network bandwidth and CPU resources to varying degrees.Static Routing and dynamic routing have their own characteristics and applicability. Therefore, dynamic routing is usually used as a supplement to Static Routing in the network. When a group is used to find the route in the vro, The vro first searches for the static route. If yes, the vro。 forwards the route according to the corresponding static route forwarding group.
