.....And the last step is to add network to the certain OSPF area.

On R1

[admin@MikroTikR1] /routing ospf network> add network=210.13.1.0/28 area=backbone
[admin@MikroTikR1] /routing ospf network> add network=10.10.1.0/30 area=backbone
[admin@MikroTikR1] /routing ospf network> add network=10.10.1.4/30 area=backbone

Instead of typing in each network, you can aggregate networks using appropriate subnet mask. For example, to aggregate 10.10.1.0/30, 10.10.1.4/30, 10.10.1.8/30 networks, you can set up following ospf network:

[admin@MikroTikR1] /routing ospf network> add network=10.10.1.0/'''24''' area=backbone

When I try to aggregate my networks error with /'''24''', I tried /24 instead is this correct.

Just do it without quotes.

Just do it without quotes.

Just tried that and while it was ok on first PTP the other end lost connectivity so back to /30

/routing ospf network add network=10.10.1.0/24 area=backbone

must be working and after that you can remove:

10.10.1.0/30 and 10.10.1.4/30. There might be small interruption after removing this.

Yes it worked initally but reboot and ospf + ip connectivity is lost,
example on say PTP link 10.10.1.0/30 eth (ip 10.10.1.2)and 10.10.1.4/30.wlan (ip 10.10.1.5) to 10.10.1.4 wlan (ip 10.10.1.6) and 10.10.1.8 eth (ip 10.10.1.9), change both to 10.10.1.0/24 all OK until you reboot then ping say eth side of ptp with ip address of 10.10.1.9 and it timeouts.
