Buonasera a tutti,
scusandomi per il ritardo propongo in lista la mia soluzione per 
l'esercizio di routing per la parte IPv6:

Fermo restando lo schema fatto in precedenza trattandosi di IPv6 non mim 
pongo il problema delle esigenze di indirizzamento  piano per piano, per 
il prefisso utilizzo un  generatore disponibile in rete che mi ha 
proposto fd93:9d78:8744, per il subnet ID scelgo di dare dei valori  che 
mi sembrano intuitivi (valorizzo i primi 8 bit a 0 i seguenti 4 in base 
all'edificio e gli ultimi 4 in base al piano) e quindi utilizzerò le 
seguenti /64:

Router			Rete IPv6

RA			fd93:9d78:8744:f::
RA0			fd93:9d78:8744::
RA1			fd93:9d78:8744:1::
RA2			fd93:9d78:8744:2::
RB			fd93:9d78:8744:1f::
RB0			fd93:9d78:8744:10::
RB1			fd93:9d78:8744:11::
RB2			fd93:9d78:8744:12::
RC			fd93:9d78:8744:2f::
RC0			fd93:9d78:8744:20::
RC1			fd93:9d78:8744:21::
RC2			fd93:9d78:8744:22::

A questo punto considero le configurazioni dei vari routers per quanto 
riguarda la configurazione IPv6 (e per le punto punto scelgo di 
utilizzare delle /127 :

Sperando di non aver commesso troppi errori mi rimetto alla clemenza 
della corte. )D
