Mikrotik SwOS Is it possible to combine ports into a single channel without a loop?

Question

Computer networks

Two buildings. There are 2 UTP cables between buildings.
The first building has a MIKROTIK RB3011UIAS-RM router, the second building has a MIKROTIK CSS326-24G-2S+RM switch. Is
it possible to combine two 1G channels to get 2G between buildings?
As far as I understand it will be a loop. Is it possible to avoid it and combine ports into a single channel with speed summation?

Answer 1

This is when there are routers on both sides.
When there is one switch, this will not work (
I did not find bounding in SwOS.
But there is LAG - I understand this is "the same thing"
The correct answer: on the side of the router we do bounding, on the side of the switch on the tab LAG include static and prescribe the group number.

Answer 2

yes, it's called bonding

Answer 3

/interface bonding add slaves='interface1', 'interface2' name="whatever you want to name the interface"
on the second side the same
after that all the rules, etc. hang on the bonding interface
