Knowing your network

You need to make a table of your equipment. Below is the format of the table. The IP address is one you will assign in lab 2 based on the network diagram, and yes you just use the network diagram to find that information.

host    interface       MAC             IP 
br      fxp0
br      fxp1                                    
r1      eth0                                    
r1      eth1
r1      eth2
r1      eth3
r2      eth1/0
r2      eth1/1
r2      eth1/2
r2      eth1/3
r3      eth1/0
r3      eth1/1
r3      eth1/2
r3      eth1/3
ws0     eth0
ws0     eth1                                    
ws1     eth0
ws2     eth0                                    
ws3     eth0

If a interface doesn't have a IP listed in the diagram, or is not connected to one of the main switch ports, just list as N/A for those columns.

On r1 and ws0-ws3 you use the ifconfig command to gather the ethernet (MAC) address which is labeled HWaddr in the output. On BR, R2 and R3 you use the show interface command. On the IOS routers (R2/R3) the second line of output has the ethernet address in the form xxxx.xxxx.xxxx. On BR the ethernet address is labeled Hardware Address.

Lab data for this report should be collected individually so you have exposure to logging into each machine via the vnc system. Lab reports are turned in individually. This part of the report is worth 15 points.

Question 1 (10 points) - Pick any two stations from the set of (BR,WS1,WS2,WS3). Show me a path a IP packet clould take between the two stations. If there is more than one available path, just pick one of them and show me that.

As an example, if you chose WS1 and WS3 you would turn in somthing like this:


Packet from WS1 to WS3

IP packet leaves WS1 eth0 
Ethernet source address: xx-xx-xx-xx-xx-xx
IP source address X.X.X.X
Ethernet destination address: xx-xx-xx-xx-xx-xx
IP destination address X.X.X.X
IP packet arrives at R1 eth1

IP packet leaves R1 eth3
Ethernet source address: xx-xx-xx-xx-xx-xx
IP source address X.X.X.X
Ethernet destination address: xx-xx-xx-xx-xx-xx
IP destination address X.X.X.X
IP packet arrives at R3 eth1/1

IP packet leaves R3 eth1/2
Ethernet source address: xx-xx-xx-xx-xx-xx
IP source address X.X.X.X
Ethernet destination address: xx-xx-xx-xx-xx-xx
IP destination address X.X.X.X
IP packet arrives at WS3 eth0

The ip addresses and MAC addresses to use are the ones that would be in the packet itself as it moves through the network.

One section describing each hop. You can choose any path available if there is more than one. You can *not* choose the example path above. (WS1 to WS3)
