關(guān)于RIP的問(wèn)題

今天用cdrouter測(cè)試了下路由器，路由器的lan和wan口都接到PC上，看了下測(cè)試結(jié)果，很多failed。但是出來(lái)的log信息，小弟看得不是太明白，還望大俠指教。
------------------------------------------------------------------------------
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。
這段話我的理解是，板子作為DHCP服務(wù)器給虛擬機(jī)器分配了一個(gè)IP:192.168.1.51,而虛擬機(jī)器帶有一個(gè)192.168.201.0的路由表發(fā)送給板子。納悶的是，這里怎么跑出來(lái)一個(gè)192.168.201.1，謝謝

使用tcpdump分析一下數(shù)據(jù)包

謝謝答復(fù)，后來(lái)我通過(guò)ethereal抓包發(fā)現(xiàn)，確實(shí)是我的板子(192.168.1.1)通過(guò)DHCP給虛擬機(jī)器分配了一個(gè)IP(192.168.1.51)，而這一句Forward packet to new RIPv2 destination 192.168.201.1，通過(guò)抓包發(fā)現(xiàn)是192.168.1.50給192.168.201.1發(fā)送一個(gè)UDP的包，這里怎么突然出來(lái)一個(gè)192.168.1.50和192.168.201.1啊，百思不得其解，謝謝

虛擬機(jī)是不是有兩個(gè)網(wǎng)卡？

jiangzj123

是有兩個(gè)網(wǎng)卡，一個(gè)接路由器的LAN口，一個(gè)接路由器的WAN口
