Multi-exit discriminator (MED) is advertised to external neighbors to try to influence path selection into an AS. For instance, consider a case where there are redundant links to an ISP and you want traffic to flow across the higher bandwidth path. Weight or LP could be used to control how local routers send traffic out of the AS, but external neighbors do not receive this information. A lower MED could be set on one path, indicating to your neighbors that they should reply o..
Configuring the Pure Point-to-Point Network
If there are many VCs, there might not be enough bandwidth at the access speed of the interface to support the aggregate EIGRP traffic. The subinterfaces should be configured with a bandwidth that is much lower than the real speed of the circuit. In this case, it is necessary to use the bandwidth-percent command to indicate to the EIGRP process that it can still function. The ip bandwidth-percent-eigrp command adjusts the percentage of capacity that EIGRP may us..
It is debatable whether OSI or IPX represented the most serious contender to TCP/IP as the ubiquitous networking technology of the future. At one time, IPX enjoyed an installed base that far exceeded IP, and numerous plans arose to build the IPX equivalent of the Internet. Novell NetWare (see Figure 1-12) is based upon a client-server paradigm, with the initial intent of sharing large disk volumes among a set of relatively meagerly equipped clients. As with Appl..
Cisco Catalyst Switch Troubleshooting Targets
Cisco offers a variety of Catalyst switch platforms, with different port densities, different levels of performance, and different hardware. Therefore, troubleshooting one of these switches can be platform dependent. Many similarities do exist, however. For example, all Cisco Catalyst switches include the following hardware components: ■ Ports: A switch’s ports physically connect the switch to other network devices. These ports (also known as interfaces) allow a switch t..
Use the NTP and clock show commands to verify the status of NTP on your router. The best place to start is the show clock detail command, which provides information on the current time, time source, and time zone configuration: Router>show clock detail 15:54:33.079 EST Sun Jan 29 2006 Time source is NTP Summer time starts 02:00:00 EST Sun Apr 2 2006 Summer time ends 02:00:00 EDT Sun Oct 29 2006 Router> To display the current NTP status of the local router, the comman..
