Hi,

Sorry for OT. I just did this in the network and it didn't work. I'm
wondering what could be wrong.

LWAPP -- WLC4404 -- Vlan200 -- VRF test -- 6509 (running IOS DHCP)

My wireless client could not get IP address from DHCP server. Debug on 6509
showed DHCPDISCOVER from client and 6509 response with DHCPOFFER but there
was no DHCPREQUEST coming back from the client. Remove VRF configuration
and it's working fine.

I tried to put IOS router (2600) on this Vlan200 and configure 'ip address
dhcp', it can get IP address from 6509. So confused.

Is there any special thing I need to do on WLC to make it work? Thank you
in advanced.

-- config on 6509 -
!
ip vrf WLAN-guest
 rd 65000:1
 route-target both 65000:1
!
ip dhcp exclude 10.1.1.0 10.1.1.15
!
ip dhcp pool guest
 network 10.1.1.0 /24
 default-router 10.1.1.1
 dns-server 4.2.2.2
!
interface gig1/1
 description ** trunk to WLC **
 switchport
 switchport mode trunk
!
interface Vlan200
 ip vrf forwarding WLAN-guest
 ip address 10.1.1.1 255.255.255.0
!

Cheers,
