Bandwidth Shaping - Fiber

I was told by Comcast that I needed to turn on “bandwidth shaping.” Comast limits my fiber by 2gbs/2gbs. According to them, if I try to pull more than their cap it will cause performance problems unless I turn on shaping from my router. I am new to Mikrotik and had to buy because of the fiber needs.

Can anyone please walk me through the process fo activating bandwidth shaping on my routeros by Mikrotik?

Really appreciate the help in advance!

Now this sounds odd… but anyway - I would do it with a simple queue:

/queue simple
add max-limit=2G/2G name=LimitMyWAN target=192.168.88.0/24

Assuming 192.168.88.0/24 is your local network.
This does not limit any client individually and only kick in when you’re saturating your fiber link - in this case, every client is limited equally.
