How to properly configure a CISCO margrutizer?

Question

Cisco

There is an ASR 1001-x - a router.
In Ge0 - the provider's cable is plugged in and IP 212.200.50.1 is set.
In Ge1 - the cable going to the local network switch is plugged in and IP 172.16.1.1 is set. The
Internet is working, the network is working, the routes are all registered.
Now you need to plug in another cable (Ge2), which will connect the second part of the local network.
In theory, on Mikrotik it was possible to combine 2 ports into a bridge and set one IP and there would be no problem.
Now, when I try to create a bridge, nothing happens.

bridge irb
bridge 1 protocol ieee
bridge 1 route ip

interface Ge1
no ip address
full-duplex
no cdp enable
bridge-group 1

interface Ge2
no ip address
full-duplex
no cdp enable
bridge-group 1

interface BVI1
ip address 172.16.1.1 255.255.255.0

Somewhere I read that BVI Cisco seemed to be abandoned altogether.
So how do you actually complete the task?

Answer 1

So and it would be desirable L2 or L3 association. My experience is that the concept of "bridge" in Mikrotik leads to a fatal dislocation of the brain in any sane networker.

Answer 2

in the end what is right?

Answer 3

I suspect that you need to do vlan
