DHCP options

RouterOS General
1

Hi…
I have trouble getting options from mikrotik dhcp.
This is how it is set-up:

[adminxx@router.xxx.hr] /ip dhcp-server option> print 
 # NAME                                CODE VALUE                              
 0 option1                             72   161.53.xx.xxx                      
[adminxx@router.xxx.hr] /ip dhcp-server option>

I dont get anything from dhcp…
I tested it with mikrotik 4.17 and 3.30…

2

Is it added to dhcp network? Does dhcp client request that option?

3

I request it and I dont get it…
It is set like this:

add address=161.53.xx.0/24 comment="" dhcp-option=option1 dns-server=161.53.xx.xx gateway=161.53.xx.x next-server=10.168.x.x ntp-server=161.53.x.x

also, I dont get NTP and I also tried with option 7…

4

enable dhcp logs and see what exactly is received/sent

I have the same problem, with option 43, the client sends the option 43 in the request list , I have this option defined and assigned to the pool, the server doesn’t send the option with the dhcp offer and the ack packets. I try it with 4.17, 5.1 and 4.16 routeros version. In bootp i try with static, dinamyc and none.
Tomorrow I will send the configuration and the dhcp debug logs .

Vendor-Specific = option 43

The log is with version 5.1

Mikrotik don’t sent mask, DNS and gateways

I reset confinguration, I configure it again and all correct , the dhcp send all options, version 4.17.
I don’t know why :frowning:
