Pure IKEv2 tunnel between linux (as a server) and mikrotik (as a client, dynamic IP)?

Question

linux

Actually this is the question.
That is, without using the ppp-family of protocols.
On the libreswan server, for example.

Answer 1

Just not IKE. IKE - Internet Key Exchange - key exchange protocol - is used to establish IPSec tunnels (using the ESP protocol for packet transport).
And so - it works only on the way! For example, now I'm sitting at home, and the "My Documents" directory is connected via an IPSec tunnel to a server that is located about five kilometers (if in a straight line) from me ...
The roadwarrior configuration is called. There are many examples on the strongswan website.

Answer 2

It's possible, it works.
