Syslinux - Nov 2002 - pxelinux using cisco router as a dhcp server

g'day,

i've been using pxelinux for a while on a bunch of machines in a lab.
i note your pxelinux site shows configuration for ISC DHCP server - you and 
others may also find this useful ..

most Cisco IOS-based routers (& some IOS-based switches) can run as a DHCP 
Server.

i use them with pxelinux with the following configuration:
	ip dhcp pool dhcppool-vlan3-host12
	   host 10.67.16.77 255.255.255.192
	   hardware-address 00d0.b74c.af68
	   bootfile pxelinux.0
	   next-server 10.67.16.5
	   dns-server 10.67.16.5
	   domain-name cisco.com
	   default-router 10.67.16.2
	   option 208 ascii "f1:00:74:7e"

in reality, the fields are:
	ip dhcp pool <name>
	   host <ipaddress> <subnetmask>
	   hardware-address <macaddress>
	   bootfile pxelinux.0
	   next-server <tftpserver_ip>		# i use this as my dhcp server has a 
different ip-address to my tftp server
	   dns-server <dns_ip>
	   domain-name <domainname>
	   default-router <default_route_ipaddr>
	   option 208 ascii "f1:00:74:7e"		# make pxelinux happy

hopefully you find this useful.
for what its worth, there are no limits to # of hosts you can add -- just 
NVRAM space for saving the configuration.


cheers,

lincoln.
