layer 7 routing

to connect other lower-layer areas Non-trunk zone: The vro inside the vro only knows the complete network topology of the local region, but does not know the network topology of other regions. At least one regional border router is required Five grouping types: Greeting (Hello) Group Database description Group Link State request Group Link State update group, which uses the flooding method

In fact, the essence of a layer-3 switch is a layer-2 switch with the routing function. The routing mainly belongs to the network layer function in the OSI reference model, so the layer-3 Switch also has the

In recent years, with the rapid development of internet/intranet and the wide application of B/S computing mode, the business of cross region and network has been growing rapidly, and the industry and users have deeply felt the bottleneck effect of traditional routers in the network. The three-layer switch can operate on the third layer of the network protocol, play the role of

Lab objectives:1. Master the configuration of the switch Tag VLAN;2. master the basic configuration methods of layer-3 switches;3. Master how to configure VLAN routing for layer-3 switches;4. layer-3 switches are used to implement VLAN visibility and mutual communication;Technical Principles:A

Differences between traditional switching and Routing After a layer-3 switch routes the first data stream, it will generate a ing table between the MAC address and IP address. When the same data stream passes through again, the table is directly routed from the second layer instead of the second layer, which eliminates

Packet Tracer 5.0 Experiment (IV.) inter-VLAN routing with three layer switchesFirst, the experimental target Master the configuration of the switch tag VLAN; Master three layer switch basic configuration method; Master three-layer switch VLAN routing config

Experiment on single-arm routing using a layer-3 Switch In the real environment, sometimes the gateway is not necessarily enabled on the router, sometimes the single-arm routing function is not necessarily connected to the interface on the router, you can use a layer-3 switch, because the vswitch itself has a variety o

period of time can be the network of routers to obtain the distance vector information on each router unified up, so that each router only need to view the distance vector table can be a different source grouping to find an optimal route. 2.Link state routing protocol is the most widely used intra-domain routing protocol. It uses a "puzzle" design strategy,that is, each router broadcasts its link state to

OSI Layer-7 model basic knowledge and common application OSI Open Source Initiative (OSI for short, Open Source code Promotion Association, Open Source code organization) is a non-profit organization designed to promote the development of Open Source software. The full name of the OSI Reference Model (OSI/RM) is the Open System Interconnection Reference Model (OSI/RM ), it is a network system interconnectio

DJango2.0 Routing Layer-urlconf The URL configuration (URLconf) is like the directory tree of the Web site that Django supports. Its essence is the mapping table between the URL and the view function to be called for the URL; For a URL that is sent by the client, which logic code is called for execution. In general, a path corresponds to a view function. It is not one by one co

I. Lab Objectives Master the configuration of the switch tag VLAN; Master the basic configuration methods of layer-3 switches; Measure the test taker's knowledge about how to configure VLAN routing for a layer-3 switch; Layer-3 switches are used to implement inter-VLAN communication; Ii. Lab b

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for

string that contains the path delimiter Registering a custom converterFor some complex or reusable needs, you can define your own converters. A converter is a class or interface that requires three points: regexClass properties, String type to_python(self, value)method, value is the string that the Class property regex matches to, and the specific Python variable value is returned for Django to pass to the corresponding view function. to_url(self, value)method,

Preface:Actually, this articleArticleI don't know what the name should be. I don't feel like I'm talking about anything. Alas... In fact, my intention is to describe the IP layer of the Linux protocol stack to route data packets. For example, if there are two Nic devices, where should the data packets go?And so on... First, understand the concept of routing cache:Although the data structure of route table

The task at the network layer is to select an appropriate inter-network route and exchange node to ensure timely data transmission. The Network Layer encapsulates the frames prov
