We are doing business router configuration, enterprise managers themselves may not understand the configuration of the router operation, structural principle resulting in a number of implementation errors, this has led to an improperly configured router for enterprises to bring the entire network performance problems. So here we have to see what is wrong operation may encounter and how to deal with.
Enterprise router configuration issue a superposition bandwidth misunderstanding
As information technology has resulted in many large enterprises need to download from time to time the operation, which led to the original ADSL bandwidth is tight; many network administrators that the multi-WAN port router, for a number of ADSL lines, which will play The role of the bandwidth superimposed.
In fact, such understanding is wrong. Multi-WAN port router and will not be ADSL line can support multiple access, and to enhance the total rate of broadband access, it is just for the corporate network to provide an effective management program; example of the distribution of different applications of ADSL lines of different need to cross-segment access, you need to backup, et al. For example: while access to Telecom ADSL and ADSL 2 line Netcom, Telecom ADSL access as stable, high transmission rate can be mainly used for data up / download the application; Netcom ADSL access to quality general, can be mainly used for information search Find.
Enterprise router configuration issue 2, DHCP service configuration bad
DHCP server, the advantage of computer users do not need any settings, more convenient for users. However, the disadvantage is that if DHCP to control a user can easily access corporate networks, but also easy to launch internal attacks impact. So for businesses, a better way to release IP addresses through DHCP, but limit the calculator to get the IP address for management.
For example: use a supported IP / MAC binding function of the router configuration MAC address to identify payment calculator specific IP, IP address so you can manage. Same IP / MAC binding function also prevents users to modify IP, in order to achieve a higher authority, and thus also prevent ARP attack.
Enterprise router configuration issue 3, interface configuration inconsistencies
Between the two router POS interface configuration, some users pay no attention to the consistency of configuration at both ends, resulting in between the router can not communicate.
Nasi Ke router, its POS interface, the default interface circuit does not allow scrambling, if one end of the configuration of the circuit while the other does not scramble, you can not communicate; therefore end routers and POS port on the exchange process, should be noted determine whether the line by way of scrambling. Scrambling to allow use of the command line: pos scramble-atm, not allowed the use of scrambling line no pos scramble-atm.
In addition, Interface MTU value should also pay attention to the configuration. Generally speaking, Cisco routers, POS port is the MTU value used in 4096, when both ends of the MTU value is inconsistent as long as one end of the MTU value of the router can be set to 1500.
Enterprise router configuration issue 4, did not take into account the configuration of the routing table
The main work is to the router through the router to find an optimum for each data frame transmission path, and transmit the data efficiently to the destination site. Therefore, the strategy is to choose the best path routing algorithm is the key to the router. To accomplish this task, all preserved in the router data transmission path - routing table.
Typically, the routing table can be fixed by the system administrator to set a good, you can also dynamically modify the system can automatically adjust the router can also be controlled by the host. Some network administrators consider the routing table is not correctly configured, the router changes the sake of other configurations, leading to more joint problems.
To view the routing table, enter the "Router # show ip route" command. Table records to C at the beginning of the record for the router directly connected to the network segment, as long as with the port address, the routing table will have this record. Although the router can communicate, but no set route, the host can not ping each other through.
Enterprise router configuration process, in addition to considering peak of performance router product itself, how to identify potential advantages of products to serve enterprise network is configured process and pay attention. Of course, the line to the article in the discussion on the topic of misconfigured router, the configuration will be involved in many aspects, such as measurement indicators EIGRP router, OSPF matching parameters, subnet password, etc. The key to understand the need to carefully configure the network administrator product description, as well as fully familiar with the enterprise network environment, so as to avoid the router configuration issues resulting from a variety of business interoperability failures.
Enterprise router configuration process more than willing to have problems on to introduce to you here and hope that you understand and master the enterprise router configuration, make corporate network structures.
