Help with inter-vlan routing

[Tuff]

Hi guys

   I am new to Cisco switching and i need some help. I have 3 vlans och 2 switches. Switch 1 has vlan 10 and vlan 20 configured on it and switch 2 has vlan 30 on it. I configured router on stick with dhcp and everything is good between the vlans and dhcp. My problem right now is that, i have a PC on the switch 2 which is in the default vlan 1. I would like to know how i can configure that pc so that it will get an ip address from the dhcp pool from the dhcp router.

Hi,

As VLAN 1 is not configured on Router. As both switches are working in L2 mode so you have to configure new VLAN 1 on the Router and configure DHCP pool for the VLAN 1. Same like you had configured VLAN 10 or 20.

Hello,

in addition to Deepak's post, and wihout wanting to be redundant, you (obviously) also need a subinterface for the native Vlan. So the entire thing would look like this:

ip dhcp excluded-address 192.168.1.1
!
ip dhcp pool Vlan1
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
!
interface GigabitEthernet0/0.1
encapsulation dot1q 1 native
ip address 192.168.1.1 255.255.255.0

Thanks everyone.. It was helpful and i was able to fix it.

Hello
An alternative to creating a additional

sub-interface

which isn't necessarily required for vlan 1

int gig0/0
ip address 192.168.1.1 255.255.255.224
exit

ip dhcp pool vlan 1
network 192.168.1.0 /26
default-router 192.168.1.1
