excluding DHCP address in vrf context

Hi all,

Does anyone know how to exclude a DHCP address for a DHCP pool in a specific VRF ?

See the following config:

ip dhcp excluded-address 172.16.0.1

ip dhcp excluded-address 172.16.0.2

ip dhcp excluded-address 172.16.0.3

!

ip dhcp pool GUEST

vrf GUEST

network 172.16.0.0 255.255.248.0

default-router 172.16.7.254

dns-server 195.238.2.22 195.238.2.21 192.168.1.1

lease 0 8

!

This doesn't work. I get assigned 172.16.0.1, even though it is excluded.

Platform: C3750, IOS version 12.2(46)SE

Geert,

If I remember correctly DHCP excluded addresses are not supported with VRF. Please see the following link under restrictions. I know this is documentation is for a router, but I assume that it applies to the switching platforms as well.
