Router-id command not showing under OSPF

[201809620]

Hello! We have a school project that requires us to connect 3 ciscos between each other, this 3 ciscos are provides by the school so varios groups are using them. The thing is, 2 of them lets us configure them without a problem - we set ip addresses and set the router id. But one of them doesn't let us. 

Let's say we set the IP address, publish our networks under the ospf protocol, but when we try to set an router id we're not allowed, the command simply doesn't show up and the connection doesn't pass that router.

They had us reset the ciscos between groups - just the command "reload" and nothing else - and I'm wondering if that command is preventing something or maybe is there another command we should use to restart the ciscos? Any input is greatly appreciated.

what exactly not accept 
router ospf command 
or 
ospf router-id 
?
if first one you need 
ip routing 
if second one, then after add router-id <IP> do clear ip ospf process

The second one, the commands we use after setting ips is:

Router OSPF x

Network x.x.x.x x.x.x.x area X 

Router-id x.x.x.x

However, when we type router id we get a "unknown line/command", but this lines work just fine with the other routers

It abnormal 

You can use as workaround 

Config loopback and then config router ospf'

The router will select this LO as router-id

On that 3rd rtr, do you have the privilege to change the router-id ?

show  privilege

It says my privilege level is 15, is that the correct level?

Yes, privilege 15 should be good enough. What type of router is that? Can you provide the model number?
