Hej

I was wondering if SRX DHCP Server can distribute IP addresses that are not in it own subnet?. So far I have been only succesful when the address-pool is in the same subnet as the SRX interface like in below. If I do change the subnet values it does not work

show interfaces ge-0/0/1  
description to-EX3400;
vlan-tagging;
unit 0 {
    vlan-id 202;
    family inet {
        address 66.66.202.2/24;
    }
}

show routing-instances OSCAR-66-1-EX3400 
interface ge-0/0/1.0;
instance-type virtual-router;
system {
    services {
        dhcp-local-server {
            group DHCP {
                interface ge-0/0/1.0;
            }
        }
    }
}
access {
    address-assignment {
        pool DHCP-66 {
            family inet {
                network 66.66.202.0/24;
                range TEST {
                    low 66.66.202.100;
                    high 66.66.202.110;
                }
                dhcp-attributes {
                    router {
                        66.66.202.1;

From the traceoptions I see the below when I try a different subnet. There are few repeating errors for Option 82 etc.

And this is when DHCP assigns an address succesfully if I set the addresspool to be same subnet as in SRX interface

Hello ODJ,

I can see that you are using JDHCP server and Legacy DHCP relay in the SRX. I would suggest you to use JDHCP relay under the routing-instance based on the following KB article - https://kb.juniper.net/InfoCenter/index?page=content&id=KB28641

If ge-0/0/1 is the relay interface, which interface is for DHCP server in the SRX?

I was using DHCP itself as the server and distribute IPs from an IP pool.

That is why I configured ge-0/0/1.0 as DHCP server interface. But at the same time it is the interface facing the client

Hello ODJ,

My Bad.

So, when you mean "If I do change the subnet values it does not work", are you changing the subnet value for ge-0/0/1 interface?

Is EX-3400 switch is deployed as L2 or L3? If it is L3 then the switch has to be configured as DHCP relay if the clients and server are in the different network.

Right now I am just testing a very straight forward setup. I have EX3400 directly connected to SRX and trying to assign an IP on the EX3400 interface.

EX3400

set interfaces ge-0/0/1 unit 202 vlan-id 202
set interfaces ge-0/0/1 unit 202 family inet dhcp update-server
set interfaces ge-0/0/1 unit 202 family inet dhcp force-discover

odj@test7ce8dk# run show interfaces terse ge-0/0/1
Interface Admin Link Proto Local Remote
ge-0/0/1.202 up up inet 66.66.202.100/24

In SRX, if the Ranges I configure under "Access" are the same as subnet (66.66.202.0/24) of SRX interface then EX3400 will get an IP. However, if I change the Network and Range to be a different subnet (like 10.0.0.0/24 range 1-2), then EX3400 will not get the IP from SRX.

This led me to believe that SRX was only able to assign addresses as long as the Range is same as its interface subnet. OR I am missing something

Hi ODJ,

Yes, you are right.

The interface's subnet and DHCP pool IP addresses should be in the same subnet. From the below KB article, it is mentioned clearly that "Clients are assigned addresses from pools with subnets that match the interface on which the DHCPDISCOVER packet is received"

Thanks. looks like the behavior is the same in new DHCP as well.

Need to change testing plans I guess 🙂
