In the network diagram for this problem, Router GW-2 is redistributing between RIP and OSPF. The OSPF domain has a different mask (longer in this case) than the RIP domain, and they are on the same major network. Therefore, RIP will not advertise rou...
Rtr A在发送更新包的时候，因为172.16.1.33/28与发送接口172.16.3.1/24同在一个主网络下，但是子网掩码不同，所以接口172.16.3.1/24不会向外通告172.16.1.33/28这一条路由。Rtr A在发送更新包的时候，因为173.16.1.33/28与发送接口172.16...
上次试验没有完全成功，因为默认路由的问题导致ROUTE-MAP匹配有时会错乱。详细描述见：http://www.mycisco.cn/post/150.html这次试验利用了PBR，来控制精确的选择出口.思路：利用PBR优先使用第一个可用接口，给每个PBR故意设置不同顺序配置：hostname r4!!ip subnet-zero!!!!!!interface Ethernet0/0 ip address 192.168.1.4 255.255.255.0 ip nat in...

CISCO路由器和LUNIX基本类似，它利用ICMP最终报告目标不可达，目的不可达结果过程：CISCO使用UDP协议，默认每次探测的源端口随即，目标端口默认33434，并且每一次探测目标端口递增。LUNIX使用UDP协议，默认每次探测的源端口固定，目标端口默认33434，并且每一次探测目标端口递增。TTL被耗尽，路由器发送TYPE=11,CODE=0的ICMP回显，表示超时，TTL＝0被耗尽。到达目标，目标发送TYPE=3,CODE=3的ICMP回显，表示网络目的不可达，端口不可达WINDOWS...
How ICMP Redirect Messages WorkICMP redirect messages are used by routers to notify the hosts on the data link that a better route is available for a particular destination.For example, the two routers R1 and R2 are connected to the same Ethernet seg...
