ccna 200 301 syllabus definition and example of hyperbole.mesh topology anymore, which is really hard to manage.That's why hybrid mesh topologies are often used in today's WANs. In fact, mesh topologies are really rare in today's applications. The primary reason for a mesh topology is that it provides a robust fault tolerance mechanism - a large number of connections are established so that if one link goes down, computers and other network devices can easily switch to many redundant (and functioning) connections. But as you can imagine, all the cables in a mesh topology can make implementation costs quite substantial. And why not, when you can greatly reduce the complexity of network management by switching to a PartialMeshTopology? You may lose a little fault tolerance this way, but you can still apply the same technology to all your network devices when using partial mesh routing. Just keep in mind that not all devices in a partial mesh topology are interconnected, so choose carefully which devices need to be interconnected.1.3.5 Point-to-Point TopologyThe name of the Point-to-Point topology indicates that a direct link is established between two routers to provide a communication path. In a point-to-point topology, two routers can be interconnected by serial cables to form a physical network, or they can be far apart and connected by a link in the WAN network to form a logical network.Figure 1.12 gives a few good examples of this: a T1 and WAN point-to-point connection.The figure shows a lightning line, two disks with arrows drawn in the center, right? The two discs with arrows drawn on them represent two routers in the network, and the lightning line represents a WAN link (these logos are built on industry standards and are used throughout the book; get familiar with them as soon as possible).1.4 Selection of topology, backbone and network segmentsThe second part of the diagram draws two computers connected by a cable one point to point chain the other. Does this make a serial connection, like between routers Do you remember anything we just mentioned ...... T1 Remember what we said about end-to-end networks? It's great to remember! I hope you remember one of the major drawbacks of end-to-end networking: poor scalability. Knowing this you won't be surprised by the following statement: twoDirectly connected Ethernet or wireless devices that use wireless to create point-to-point links also do not scale well with the network. In today's WAN networks, you see many point-to-point networks and, as shown in Figure 1.12, Part III, connections between computers and hubs or switches thatB! cable hubs connected directly to hubs or switches are also point-to-point links. The three point-to-point connection scenarios in Figure 1.12 using this type of connection are typically: a directly connected wireless connection between two wireless bridges for connecting
