18、. As shown in figure 3.2, we will connect the four subnets (, , , and ) using three routers.In order to configure the new network topology, we need to change the current IP addresses of each PC interface card. The new IP addresses that we want to

19、 use are as shown in the figure. (Note that 52.100 is an abbreviation for 00. This notation applies to all the PC and router addresses given in the figure above.)June 13th, 2001Magda El Zarki - TCP/IP Lab22ConfigurationEth0:51.1Eth1:52.1Eth0: 53.2Eth1: 52.2Eth0:53.3Eth1:54.353.10051.10054

Also configure the routers. Save the output of netstat -rn or route ee before building the PCs routing tables. After examining the figure, build the static routing tables in all the PCs manually. Use netstat rn or route ee to verify your entries.nUse the ping and traceroute programs to test the connections. Save th
