DHCP Static route

Hail!

 

Is there any way to change the subnet mask configuration on a manually added

static route on a DHCP server (Windows 2000 ou 2003) to one different than

/32 (i.e. /16)?

 

Thanks!!!

RE: DHCP Static route

 

Aidemin,

 

I am a bit confused by your question as DHCP doesn't deal with routes. I

will tell you that DHCP is not tied to any specific subnet mask and can use

any valid one you give it. (/32 wouldn't work of course...) So, a change to

any of the valid values that DHCP is pushing out would take effect the next

time the workstations take a lease.

 

If you have workstations that are statically set, the DHCP server will not

be able to address them as it will only provide addresses and setting to

machines configured to abide by the DHCP settings.

 

I took as guess at what you're really asking, so please feel free to clarify.

Re: DHCP Static route

 

Ryan,

Thanks for replying.

 

If you go to DHCP Options or, on an address reservation on the same DHCP

Options, tab General, you can go to the option number 033 (Static Route

Option). On this option you can specify a destination address/router

address( ie. 172.16.0.0/10.0.0.1).

The problem is, even though the option is configured and implemented

successfully, the route specified is auto-configured with a /32 subnet mask

(255.255.255.255), thus, not reaching a /16 network as per specified in my

example.

My question is if there is any way to change this subnet mask to a more

specific one through registry or any other tool.

I have noticed that this "issue" occurs on either Windows 2000 Server or

Server 2003 DHCP Servers (I could not yet perform the test on the Longhorn).

 

Again, I thank you guys for the attention.

Re: DHCP Static route

 

 

Hi all,

 

I had the same problem.

I fixed it by using Option 249 (the last in the list) through which you

can define a specific network mask.

This option is called <Classless static routes> in the way you must

determine the network mask.

The option 033 corresponds to <Classfull static routes> for which the

network mask is deducted according IETF RFQs.

Working fine...

 

Hope this will help.

 

Look at this
