在思科(Cisco)系列路由器上,show ip route 这个命令是一个非常常用并且十分重要的命令。里面可以查看该设备的当前直连的或者学习到的全部路由信息,即路由表:routing table。该命令后面可以接多个可选项,包括:[address [mask] [longer-prefixes]] | [protocol [process-id]]等。 若需使用该命令,你应当通过命令行进...
A. 120 is the bandwidth allocation and 3 is the routing process number.B. 120 is the administrative distance and 3 is the metric for that route.C. 120 is the value of the update timer and 3 is the number of updates received.D. 120 is the UDP port for forwarding traffic and 3 is ...
This path selection process depends on the destination IP address of the packet received and the knowledge that the Router has about reaching that destination. Routing and Routing Tables The “knowledge” that a Router has about the way to reach destination networks is stored in the “Routing Tab...

另外就是病毒或者攻击导致你的缓存中没有match的条目,也会进行process switch。arp input举个例子,就是你的缺省路由指向了一个广播接口,那么大量的数据包会产生很多arp的请求,建议指定下一跳的IP地址。#sh plat cpu pack stat allPac 50、kets Dropped In Hardware By CPU Subport (txQueueNotAvail)CPU Subport...
ip input是路由器使用cpu进行process switch的。当cef关闭,或者其他的快速交换的方式关闭了,那么海量的数据包都要通过中央cpu来处理,可能会消耗很多的资源。 另外就是病毒或者攻击导致你的缓存中没有match的条目,也会进行process switch。 arp input举个例子,就是你的缺省路由指向了一个广播接口,那么大量的数据包会产...
