关于RIP的问题

jiangzj123

今天用cdrouter测试了下路由器，路由器的lan和wan口都接到PC上，看了下测试结果，很多failed。但是出来的log信息，小弟看得不是太明白，还望大侠指教。
------------------------------------------------------------------------------
Test cdrouter-189: Verify router learns new RIP routes from LAN side RIP router (v1 or v2)
Module: rip.tcl
Name: cdrouter_rip_2
Description:


    step 1. Start new DHCP client on LAN interface
    step 2. Announce new RIPv1/v2 route with metric 1 from new DHCP client
    step 3. Forward from original LAN client to IP address within the
            new RIPv1/v2 route range
    step 4. Verify the packet is forwarded to the new DHCP client

我的路由器板子的IP是192.168.1.1。
这段话我的理解是，板子作为DHCP服务器给虚拟机器分配了一个IP:192.168.1.51,而虚拟机器带有一个192.168.201.0的路由表发送给板子。纳闷的是，这里怎么跑出来一个192.168.201.1，谢谢

使用tcpdump分析一下数据包

谢谢答复，后来我通过ethereal抓包发现，确实是我的板子(192.168.1.1)通过DHCP给虚拟机器分配了一个IP(192.168.1.51)，而这一句Forward packet to new RIPv2 destination 192.168.201.1，通过抓包发现是192.168.1.50给192.168.201.1发送一个UDP的包，这里怎么突然出来一个192.168.1.50和192.168.201.1啊，百思不得其解，谢谢

虚拟机是不是有两个网卡？

是有两个网卡，一个接路由器的LAN口，一个接路由器的WAN口
