Unanswered Question
Nov 23rd, 2007

I have a router with 2 subinterfaces.

interface GigabitEthernet0/0.1

encapsulation dot1Q 20 native

ip address 130.130.130.1 255.255.255.0

ip helper-address 192.168.1.5

interface GigabitEthernet0/0.99

encapsulation dot1Q 99

ip address 120.120.120.43 255.255.255.248

ip helper-address 192.168.1.5

I have a 3750 level 2 with this vlans.

interface Vlan99

ip address 120.120.120.41 255.255.255.248

ip helper-address 192.168.1.5

interface Vlan20

ip address 130.130.130.10 255.255.255.0

ip helper-address 192.168.1.5

I have the AP is connected to a port in the 3750

interface FastEthernet1/0/47

switchport trunk encapsulation dot1q

switchport trunk native vlan 99

switchport trunk allowed vlan 20,99

switchport mode trunk

Users connected to the 3750 ports vlan 20 can get IP from the range 130.xx

I want users connected to the access point to have IP's from range vlan20 (130.xx) (the same that the users connected to the 3750)

HOw can i do it?

I have this problem too.

Instead of using the trunk parameters on the fastethernet interface inself you have to use subinterfaces on the wap also . You will have to use subinterfaces on your bridge interfaces also.
