DHCP Server

[MSSK]

Hi ,
I have a linux box that simulate a DHCP server for WiMAX CPEs
The version is
Linux version 2.6.18-238.12.1.el5 (centos.org)
My concern is that i want to send the DHCP option 26 (MTU size) in the DHCP offer
Below is the configuration file
# DHCP Server Configuration file.
# see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
ddns-update-style none;
#ddns-update-style interim
#ignore client-updates
#always-broadcast on;
authoritative;
default-lease-time 10800;
#max-lease-time 10800;

ping-check true;

deny duplicates;

#log-facility local6;

shared-network wimax {

subnet 192.168.30.0 netmask 255.255.255.0 {
}

subnet 109.107.136.0 netmask 255.255.248.0 {

# --- default gateway
option routers 109.107.136.1;
option subnet-mask 255.255.248.0;

option domain-name "mssk.com";
option domain-name-servers 109.107.128.101, 109.107.131.171;

option time-offset -18000; # Eastern Standard Time
#option interface-mtu 1440;
range 109.107.136.120 109.107.143.254;

What should i add to ensure that the option is sent via the offer?

Thanks

Why are you worried about the MTU settings?
Is there a special need for this?

Hi , Thanks for the reply
yes actually i am in need of this as the setup I have needs this
I have the WiMAX GW (ASN GW) is configured with 1472 MTU and does not support fragmentation
So , I have to pass by the CPEs individually to change the MTU to cope
I want this to be sent via my DHCP server

The setting should be;

option interface-mtu 1472;
