I am trying to run the 2600 router as a DHCP server for 6 VLANs. I have setup the router and one switch for testing. I have three total switches (all 2950) and two access points (AIR1231G) to setup eventually but would like to make it work on one switch before trying to complicate things further.
If I manually assign an IP address (192.168.2.x) to the PC I can ping every device all the way back to the modem (192.168.7.254) and out to the internet. If I try to get an IP via DHCP I get a private ip (169.254.x.x). DHCP is not working.
I am not sure what step I am missing but I have tried several things and I obviously am missing something. Please help me out with a set of fresh eyes.
My path is as follows:
AT&T DSL MODEM
v
CISCO 2621 ROUTER
v
CISCO CATALYST 2950T SWITCH
v
PC
Modem is connected to FA 0/1 on the router.
Switch (Port FA 0/1) is connected to FA 0/0 on the router.
I have six sub interfaces/VLANs configured on FA 0/0
192.168.1.x - 192.168.6.x
IP designations are as follows
Modem is on 192.168.7.0 network
Router and switch are on 192.168.1.0 network
PC is on VLAN 2 which is on 192.168.2.0 network
