Now start Ethereal on workstations C or D. Let it run for 2-3 minutes. Then stop and analyze it. On workstation C or D you should see something like this: You will have to expand the tree [+] buttons to see all of this information. Notice how we can see the metrics and their values here. Hmm…looks good. You can see our default metrics with IGRP are: delay set to 100, bandwidth set to 1000, MTU of 1500 bytes, reliability set to 255, and load set to 1. Hop count here is not a metric, per se, but a device to measure how far it is from here to the “entry point for the network.” Another way to view our default metrics is with the show interface command. Here is an example of the first five lines of output: ritchie#sh int ethernet0/0 Ethernet0/0 is up, line protocol is up Hardware is AmdP2, address is 0002.fd45.ac80 (bia 0002.fd45.ac80) Internet address is 202.150.100.1/24 MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec) ARP type: ARPA, ARP Timeout 04:00:00 295
5. Now let’s try to see how workstation “A” is routed to workstation “B” by using trace route from the DOS prompt: C:\WINDOWS\Desktop>tracert 200.150.101.2 Tracing route to STAR10616125 [200.150.101.2] over a maximum of 30 hops: 1 2 ms 1 ms 1 ms 200.150.100.1 2 25 ms 25 ms 25 ms 201.150.100.2 3 25 ms 25 ms 26 ms 202.150.100.2 4 49 ms 49 ms 50 ms 201.150.101.1 5 60 ms 60 ms 60 ms STAR10616125 [200.150.101.2] Trace complete. C:\WINDOWS\Desktop> The “crucial” step in our trace is in bold above. We can see the path is through the lower Ethernet path in our diagram. We can actually statically configure the Ethernet 1 interface (on ritchie) to pass the packets through Ethernet 1 by lowering (or raising) the specific metrics to make the 203.x..x.x. route more desirable. Likewise we could also raise (or raise) the metrics on Ethernet 0 to make it less desirable. 6. Let’s start by making the 203.x.x.x more desirable by increasing the delay on Ethernet 0 from 1000 to 10000. Since there is a longer delay on Ethernet 0 (which we statically set) then the 203.x.x.x network would become the preferred route (with all other metrics being equal). ritchie(config)#int e0/0 ritchie(config-if)#delay 10000 7. Now we can repeat our trace and see if it works the way we want (to force the path over the 203.x.x.x network): C:\WINDOWS\Desktop>tracert 200.150.101.2 Tracing route to STAR10616125 [200.150.101.2] over a maximum of 30 hops: 1 1 ms 1 ms 1 ms 200.150.100.1 2 68 ms 25 ms 25 ms 201.150.100.2 3 25 ms 26 ms 26 ms 203.150.100.2 4 49 ms 49 ms 49 ms 201.150.101.1 5 59 ms 59 ms 59 ms STAR10616125 [200.150.101.2] Trace complete. C:\WINDOWS\Desktop> 8. Bingo! Just what we had hoped for…Let’s check this with Ethereal. 296
