Titolo: Aiuto per configurazione routers!

Ciao a tutti.
Devo fare la configurazione di 5 routers in una LAN per una esercitazione ma
sono in panne e non so cosa fare.
Praticamente bisogna stabilire una subnet mask e mappare degli indirizzi IP
per poi immettere i dati nei file di configurazione
dei routers.
Ecco il problema, ed a voi geni la soluzione, io ho provato diverse
soluzioni, ma niente che funzioni bene.
(Scusate per l'Inglese, se qualcuno non capisse qualcosa e' sufficiente
scrivermi!)
Problema:
Your company has been assigned the class C ip address 192.0.1.0. You need to
subnet this address so that it will provide 8 networks with the maximum
number of host addresses on each subnet. Use the same names lab-a through
lab-e and each interface that has an IP address will be assigned an address
from the appropriate subnet. You should have the configuration for each lab
saved as a text file on a floppy disk so that we can load them and test
them. Be sure to include comments that indicate your name at the top of each
lab. You may use the configurations for labs a-e on the bottom of this page
as a guide.
Questi sono i testi dei file di configurazione:

Se qualcuno fosse in grado di aiutarmi gliene sarei veramente grato.
Distinti saluti,

 number of host addresses on each subnet.
..
Se ho capito bene devi ottenere 8 subnet dalla rete: 192.0.1.0 /24
ogni subnet avrà 30 host
- 192.0.1.0 / 27 (255.255.255.224) broadcast 192.0.1.31 
- 192.0.1.32 /27 broadcast 192.0.1.63
- 192.0.1.64 /27 ...
- 192.0.1.96 /27 ...
- 192.0.1.128 /27 ...
- 192.0.1.160 /27 ...
- 192.0.1.192 /27 ...
- 192.0.1.224 /27 ...
poi sostituisci opportunamente gli indirizzi
dei router dalla conf di esempio
ciao e buon lab
