Does RouterOS support RFC3021 for point to point links? (31bit masks)
I don’t know, never tried it. But, MT does support an even more efficient method.
You can just use /32s, the addresses don’t have to be adjacent, and they can be reused on multiple interfaces.
i.e.:
router1
/ip address add address=1.1.1.1/32 network=2.2.2.2 interface=to-router2
/ip address add address=1.1.1.1/32 network=3.3.3.3 interface=to-router3
router2
/ip address add address=2.2.2.2/32 network=1.1.1.1 interface=to-router1
/ip address add address=2.2.2.2/32 network=3.3.3.3 interface=to-router3
router3
/ip address add address=3.3.3.3/32 network=1.1.1.1 interface=to-router1
/ip address add address=3.3.3.3/32 network=2.2.2.2 interface=to-router2
3 point-to-points, using only 3 addresses; /31s would require 6, and they would need to be in pairs.
With more links, it becomes drastically more efficient.

good! i always missed some kind of “unnumbered” connection.
this should be a perfect replacement.
(it’s not mentioned in the manual particularly, is it?
And you can use OSPF on these links to. Just don’t forget to specify the interface as being point-to-point.
Or, on older (2.8) systems where that isn’t an option, encapsulate it in a PPP link of some sort (l2tp, etc…), works like a charm (usually).

I didn’t think of that, and I do plan on implementing OSPF. Thanks..
