DHCP option space test

[Surya Teja]

Hi Peter,
Thanks for Reply, sorry because of other issues I was unable to concentrate
on this option space modules,
In short you need to add "vendor-option-space optionSpacedb;" in the same
block as where you use the options.  ------------>
As suggested I understood that we need to mention statement
vendor-option-space optionSpacedb; to make it perfect utilization Thanks
for suggestion
But I have a doubt, I have followed the one of the forum and in that it
mention to construct the config like below
-------------my local dhcp server config--------------------
default-lease-time 3600;
authoritative;
option proxyDetails code 252 = text;


*option space optionspacedb;option optionspacedb.option1 code 1 =
ip-address;option optionspacedb.option2 code 2 = ip-address;*


*option space optionspace2;option optionspace2.option1test code 1 = text;*



*if option vendor-class-identifier = "Avaya"{  # taking just as example
       vendor-option-space optionspacedb;}else if option
vendor-class-identifier = "avaya2"{   # taking just as example*

     *vendor-option-space optionspacedb2;**}*

subnet 192.168.0.0 netmask 255.255.255.0 {
pool {
     range 192.168.0.2 192.168.0.200;
}
max-lease-time 600;
option domain-name "example.com";
option domain-name-servers 192.168.x.xxx,192.168.y.yyy;
option local-proxy-config "http://zzzzzz";

*option optionspacedb.option1 6.6.6.6;option optionspacedb.option2 5.5.5.5;*

*option optionspace2.option1test "test";*
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;
}

It says to mention some thing like if else if statements at global section
and specify the options in pool. The client matching the vendor class
identifier can only get  optionspace values
Is the syntax right? can we construct like this for effective utilization


Thanks
