DHCP manual binding clarification

Hello experts,

need a clarification regarding this DHCP manual binding example on Cisco 1802 router. My question is will this manual binding configuration work? or will we have a problem because the manual binding is overlapping with the excluded range?

no ip dhcp use vrf connected

ip dhcp excluded-address 10.222.167.0 10.222.167.99

ip dhcp excluded-address 10.222.167.201 10.222.167.255

!

ip dhcp pool Holzwickede-1

   network 10.222.167.0 255.255.255.0

   domain-name xxxxxxx.com

   dns-server 10.1.10.21 10.224.123.4

   default-router 10.222.167.1

!

ip dhcp pool Holzwickede-Reserved-1

   host 10.222.167.250 255.255.255.0

   hardware-address xxxx.xxxx.xxxx

!

Quick answers appreciated because I have to implement this on our clients router today. Thanks a lot in advance.

Re: DHCP manual binding clarification

Hi,

If you want to allocate an IP from a scope it must not be excluded so you have to modify your excludded addresses like you've done.

DHCP manual binding clarification

Hi,

if the manual binding is for an excluded address it won't work.A manual binding is  just a special allocation but it is still an allocation and you can't allocate what you exclude from the scope.

DHCP manual binding clarification

Hi Alain,

Thanks for the quick update, so do you suggest me to configure the excluded range like this?

ip dhcp excluded-address 10.222.167.0 10.222.167.99

ip dhcp excluded-address 10.222.167.201 10.222.167.249

ip dhcp excluded-address 10.222.167.251 10.222.167.255

or is there a better way to avoid the excluded range conflicting with manual binding?
