Learn about the CCIE Routing Protocol

Self-taught CCIE route protocol troubleshooting 01. What protocol does RIP transmit information and what mechanism is used to calculate the optimal route? RIP updates route information based on UDP port 520 using the BELLMEN-FORD algorithm. The basic principle is to follow the minimum hop count principle. Therefore, the route table path is not necessarily the optimal path. 02. In a non-broadcast environment, what commands can be used to send and recei

Principle and difference of two-layer switching, three-layer switching and routing

Two-tier switch:Two-layer switching technology is the development of more mature, two-layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address forwarding, and these MAC addresses and corresponding ports recorded in their own internal address table.Specific as follows:(1) When the switch receives a packet from a port, it reads the source MAC address in the header, so that it knows th

Concept Analysis: Switching, routing and layer-3 Switching

In order to adapt to the challenges brought by the deepening of network applications, the scale and speed of the network are rapidly developing. The speed of the LAN has increased from 10 Mbit/s to 100 Mbit/s, currently, Gigabit Ethernet technology is widely used. In terms of network structure, it has also evolved from the LAN of shared media to the current LAN. The exchange LAN technology enables dedicated bandwidth to be exclusive to users, greatly improving the efficiency of LAN transmission.

destination address, which may be different routes that are learned by multiple routes by different routing protocols. Although each routing protocol has its own metrics, the metric values between the different protocols have different meanings and are not comparable. The router must choose the best path computed by one of the routing protocols to join the

Layer-3 switching and dynamic routing, half-arm Routing

Inter-VLAN Routing: One physical connection per VLAN, one-arm routing, three-layer switching

Inter-VLAN Routing 3 ways: One physical connection per VLAN, one-arm routing, three-layer switching.One physical connection per VLAN: A separate interface is assigned to each VLAN on the router, and a physical link is used to connect to the Layer two switch. When the host between the VLANs needs to communicate, the data is routed through the router three layers and forwarded to the host within the destinati

Application point of view: There are some tips for choosing the routing and switching machine

The routing switch all-in-one machine makes the user group more convenient and fast. We can use it to replace the router function. However, when selecting the routing switch all-in-one machine, you must pay attention to it to suit your needs. Vrouters and vswitches are both very mature products. Vswitches mounted under vrouters are a mature application model with a distributed design. The switch module has

Next talk about routing and switching

Routing and switching are two important concepts in the online world. Traditional switching occurs on the second layer of the network, that is, the data link layer, while routing occurs on the third layer and network layer. In the new network, intelligent routing and

Comparison of layer-2 switching and routing technologies

development status is satisfactory. Therefore, the focus of selection is not at this level. However, as the core of the network, there is no substantial breakthrough in the router technology that acts as the interconnection between networks. Therefore, a new routing technology came into being-layer-3 switching technology, which is a routing technology because it

Layer 3 switching and Routing

-transmission, improving transmission efficiency and transmitting user data point-to-point, other nodes are invisible. However, layer-2 exchange also has its weaknesses, including the inability to effectively solve problems such as broadcast storms, inter-network interconnection, and security control. Therefore, the VLAN Virtual LAN technology on the switch is generated.2. layer-3 Switching The L2 Switch works on the data link layer, the second layer

Comparison between "switching" and "routing"

Routing and switching are two important concepts in the online world. Traditional switching occurs on the second layer of the network, that is, the data link layer, while routing occurs on the third layer and network layer. In the new network, intelligent routing and

Fast retrieval problem of massive routing table-hash/trie/fast switching

combine their advantages, it is easy to think of the hash algorithm conflict linked list to trie, so that the meaning can be done in advance to understand the match or mismatch, do not match the words to enter the next hash bucket, the conflict linked list of trie statistics, ahead of the perception of "rapid failure", Unless your route entry prefix is 32-bit itemized, otherwise, there is always a time to fall back to the 24-bit prefix bucket, 16-bit prefix bucket ... Anyway, it's better than s

Cisco advanced routing with Switching (Cisco section) 1–2 days

three switching technology is the technology that combine routing technology with switching technology. After routing the first data stream, theIt will generate a map of the MAC address and IP address, and when the same data stream passes again, it will be directly from layer two through this tablerouting, which elimi

Ultra High Speed: optical switching/Optical routing creates all Optical Networks

source node to the target node is always in the optical domain, and the wavelength becomes the most basic building block unit of the all-optical network. Because all signal transmission in all optical networks is carried out in all optical networks, all optical networks have signal transparency. It implements route selection through wavelength selection devices. With its excellent transparency, wavelength routing characteristics, compatibility, and s

As the core of routing equipment, Routing Switching equipment becomes more and more important in enterprises, especially in networking applications. Here we have analyzed the common problems of Routing Switching devices in applications. As the core equipment of the enterpris

How to Use MRTG to monitor routing and switching devices (1)

The work done by a truly qualified network administrator should not be limited only after a network fault occurs. Although it is not too late, the loss is inevitable. So, how can we effectively monitor the network status, identify network faults in the first time, prevent problems in the network, and rationally divide bandwidth resources? Monitoring Network Traffic can effectively solve the above problems. Now I want to introduce MRTG, an expert in the network traffic monitoring field. In this a

How can we meet the challenges of routing networks and switching technologies?

In the past, vrouters and hubs were often used in the network, but now many networks use vswitches. How do I face the challenges of routing networks and switching technologies? Currently, vswitches are dominant in the network market, because of their high cost effectiveness and flexible structure. They can be flexibly configured with future application changes. Numbers can best indicate problems. In a vswit
