SBB-ov ruter ide na fa0/0 na cisco-u. Na sbb-u je ukljucen DHCP, dok je na portu fa 0/0 ukljucen DHCP klient i port lepo dobija od rutera adresu, i internet radi, odnosno pingovanje prema internetu. Sa porta fa 0/1 ide na cisco switch na port 0/24 koji pripada VLAN-u 1. sa porta 0/23 koji pripada VLAN-u 2 ide na komp. Na ruteru je podesen sub interfejs koji ima adresu iz opsega DHCP pool-a koji ima oznaku 0/1.1 i engapsulacija je dot1q sa vlan-om 2. DHCP pool je sa opsegom 192.168.2.0/24 gde su izbacene adrese od 1 do 5 jer je adresa VLAN-a 2 na switch-u .2, a adresa 0/1.1 je .1. Kao default-router sam probao da stavljam adresu koju dobijem preko dhcp-a na portu 0/0, pa sam probao da stavim adresu sbb-ovog rutera, pa adresu sub interfejsa. U svakom slucaju komp dobije IP adresu, ali ne mogu da dobijem izlaz na net sa racunara, dok sa rutera mogu.
