dva VLAN-a na switch-u treba da dobiju IP adrese od rutera

Pozdrav,

Ucim, i naisao sam na problem kod vise VLAN-ova. Situacija je ovakva:

router - switch - radne stanice

router je ujedno i DHCP server. switch ima dva VLAN-a prvi na portovima fa0/1 - 0/4, a drugi na fa0/5 - 0/8. Povezan je sa ruterom preko porta fa0/24. taj port je trunk i prima sve VLAN-ove. Na ruteru su postavljeni subinterfejsi koji imaju IP adresu. Ono sto je problem jeste to sto hostovi na VLAN2 koji obuhvata portove od 1 do 4 lepo dobijaju IP adrese od DHCP servera, dok oni hostovi koji su na VLAN3, odnosno na portovima od 5 - 8 nikako ne mogu da dobiju adrese.
