OVPN-Server netmask different mask 32

Configuring the OPVN Server in any configuration, in any. It doesn’t matter what I do, got it?
If you managed to make a configuration in which the interface rises with a mask different of 32, please share your experience?

example:
[admin@MikroTik] > /interface ovpn-server print
Flags: X - disabled, D - dynamic, R - running

NAME USER MTU CLIENT-ADDRESS UPTIME ENCODING

0 DR User1 1500 ..207.97 1h4m48s AES-128-CBC/SHA1

[admin@MikroTik] > /ip address print
Flags: X - disabled, I - invalid, D - dynamic

ADDRESS NETWORK INTERFACE

~~
7 D 172.16.30.1/32 172.16.30.2

with such a configuration, OSPF cannot work
