The distribution layer controls the flow of network traffic using policies and delineates broadcast domains by performing routing functions between virtual LANs (VLANs) defined at the access layer. 3. The core layer of the hierarchical design is the high-speed backbone of the internetwork. The core layer is critical for interconnectivity between distribution layer devices‚ so it is important for the core to be

CONFIGURING A SWITCH AND ROUTER IT/242 INTRO TO WAN TECHNOLOGY Date: 12/23/2012 Switches are layer 2 devices and this makes them easier to configure than routers. Most of the time‚ the default configuration with switches will enable it to connect to PCs and servers together easily. These are the steps to begin configuring your switch: 1. Connect a console terminal to the console interface of your supervisor engine. 2. After a

(1.) Compare and contrast switches‚ routers‚ and gateways. Bridges operate at the data link layer. They connect two or more network segments that use the same data link and network protocol. They understand only data link layer protocols and MAC addresses. They may connect the same or different types of cable. Routers operate at the network layer. Routers connect two or more network that use the same or different data link protocols‚ but the same network protocol. They may connect the same or

links of the various regions. Unfortunately‚ the consultant did a poor job with the integration resulting in a poor IP address scheme as a result routing tables at the summarization points and at the San Francisco Campus was very large. In addition‚ no VLAN structure was developed to isolate broadcast traffic. Also‚ there has been some concern that the WAN transport was not able to accommodate the network traffic. Finally‚ all addresses in the network was statically assigned resulting in high administration
