DHCP problem on 2811

Hello all,

I have implemented a CISCO 2811 ISR in our network. I configured a DHCP on the router but it is not working. None of the clients are able to get a DHCP address from this 2811. Here is how I have configured the DHCP.

ip dhcp smart-relay

ip dhcp use vrf connected

ip dhcp use vrf remote

ip dhcp binding cleanup interval 600

ip dhcp excluded-address 10.0.0.1 10.0.0.239

!

ip dhcp pool INTERNAL

import all

network 10.0.0.0 255.255.255.0

dns-server aa.bb.cc.dd x.y.z.s

default-router 10.0.0.1

lease infinite

!

Am I doing something wrong?

Please suggest.

Re: DHCP problem on 2811

Well i do not doubt DHCP server does not work normally. To release IP address from DHCP server, server should compare giadd with clinet subnet network.

IS this interface connected into 10.0.0.0/24 sunbnet ?

To verify DHCP packet works properly, command

"debug ip dhcp server packet".

If you see dhcp discovery packet from clinet, it's okay. Then must see dhcp offer packet.
