RTA路由器的配置.ppt

配置单区域 OSPF Router(config-router)#network address mask area area-id 指派网络到特定的OSPF区域 Router(config)#router ospf process-id 定义OSPF路由协议 OSPF优先级的配置和检测 配置： Router(config-if)# ip ospf priority number 检测配置： Router# show ip ospf interface type number 配置环回(loopback)地址 在开启状态下环回地址是不会down的。为了可靠、更高的ID可以配置一个环回地址，保证路由器的稳定。 Router(config)# interface loopback number Router(config-if)# ip address ip-address subnet-mask OSPF 配置实例 Router#show ip ospf interface 验证 OSPF 配置 显示 area-ID 和邻接信息 Router#show ip protocols 验证OSPF的配置 Router#show ip route 显示路由器学到的所有路由 Router#show ip ospf neighbor 基于每接口显示OSPF邻居信息 * 52 * Purpose: The figure shows how the IGRP commands operate on the example network. Emphasize: An administrator only specifies directly connected networks that he wishes to publish to other routers. Without the network command, nothing is advertised. With a network command, the router will advertise every subnet within the Class A, B, or C network specified in the configuration. * Purpose: This figure shows how the show ip protocol command is used to monitor IGRP operation. Emphasize: The command displays the routing protocols that are active on the router for IP. It also gives network and timer information. In this example, IGRP is displayed. Point out the timing information. Point out the list of networks for which the router is injecting routes. Point out the administrative distance metric. * Purpose: This figure displays the show ip route command which displays the contents of the router’s IP routing table. Emphasize: This is the same command presented earlier in the chapter. Discuss the IP routing table in detail. The [100/90956] represent the administrative distance and metric, respectively. Discuss the following fields: I—Refers to routes learned from IGRP. via—Refers to the router that informed us about this route. 00:00:23 timer value—IGRP updates are every 90 seconds. Ask, “How long until the next update?” The interfaces to used for the best path. Pur
