cisco router and switch simulator

large-scale network construction. Huawei and Cisco are the main product manufacturers of mpls vpn technology from the current use of routers and switches in enterprise and e-government networks. From the network products of Huawei manufacturers, the corresponding vrouters and vswitches meet the performance requirements. For example, the Huawei vronene80/40/16/08/05 can be P/PE, and the S8016 layer-3 vswitch can be PE. From the network products of

[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 layer-3 switches so t

Cisco switches enable port speed limiting As shown in, Node switch 3550 is placed in an office room. The networks of all office companies are from this place. How does the operator configure network bandwidth settings for each company on this device? Let's take the IT Training Center of XX foreign companies as an example. The IT Training Center of XX foreign companies applied for a 2 m link. Step-1 Rongxi

After the FLASH space is insufficient, I specially query the hardware configuration of the 6509 core device. The default Flash of the 6509 standard configuration is 64 MB, and the standard IOS size is 32.1 MB, the IOS 12.2 (17a) SX version to be upgraded has a size of 40.6 MB. In this case, it seems that the space is insufficient. However, this problem is well solved. The original IOS in Flash is deleted and then uploaded. So enter the command: Router

protocol is complex and cannot be processed by pure hardware chip, the performance of data forwarding is less than three layers (multilayer) switch. Tips: In fact routers have similar techniques, such as the Cisco Fast Forwarding mechanism (Cef-cisco Express forwarding) It is also the difference in working patterns that results in some differences in their act

principle of the switch MAC Address table. The second part is: three-layer exchange. This is the focus of the entire switch technology learning, but also in the work behind the most commonly used technology, in this contains 3 large chunksThe first piece is ; VLAN Partitioning and routing between VLANs. The second piece is STP: Primarily to prevent switch loops
