Hello,

I am trying to get dhcp clients to pxe boot via our cisco 1811 router. I would like to use the router as the pxe server for the initial connection due to various issues that will not allow other solutions. The router is setup with an ip of 10.59.120.1 255.255.255.0. The dhcp pool for the clients is setup as follows:

ip dhcp pool testpool
   import all
   network 10.59.120.0 255.255.255.0
   bootfile initrd
   default-router 10.59.120.1
   option 60 ascii "PXEClient"

I have the bootfile located on the router's flash card (flash: initrd). I have made sure that ip bootp server is enabled on the router and that spanning-tree portfast is enabled on the port that the dhcp client is connected to.

I currently get an ip address of 10.59.120.2 255.255.255.0 when trying to pxe boot, however I then get the error PXE-E55: ProxyDHCP service did not reply to request on port 4011.

Is there something I am missing in my config? Is it even possible to do what I am trying to do?

Any help would be greatly appreciated.

Bootp server is not ment for PXE boot. Is something else. The bootfile for bootp contains IP gateway information and additional parameters such as where startup files can be found and how to get them.
(Is very old way to do this. DHCP has many more options). In bootp you can configure things like autoexec.bat and where boot files like commanc.com can be found. Are you still using DOS?

You need a PXE server, like Altirus, for that as far as i know. It looks like bootp, but with option 60 you tell the client where the pxe server is located. The PXE file can be obtained there.

Thanks for the info. I've managed to get a solution working that has our clients booting to a novell pxe boot server using the following two commands on the cisco router:

bootfile nvlnbp.sys (this points the clients to the novell pxe boot file)
next-server XX.XX.XX.XX (this is the ip address of the novell pxe boot server)

This solution requires nothing to be done to the switches. It does require this information to be in the dhcp pool of every vlan that you want to be able to pxe boot.
