Support for RouterOS v7

[bramwittendorp]

Description of Issue/Question

The BGP syntax has changed between RouterOS v6 and RouterOS v7. The bgp-functionality in this driver is not working on RouterOS v7.

Setup

napalm-ros version

(Paste verbatim output from pip freeze | grep napalm-ros between quotes below)

napalm-ros==1.2.6

ROS version

(Paste verbatim output from /system package print between quotes below)

7.15.1 (but applies to all 7.x versions)

librouteros version

(Paste verbatim output from pip freeze | grep librouteros between quotes below)

librouteros==3.2.1

python version

(paste output of python --version)

Python 3.9.18

Steps to Reproduce the Issue

Could you paste output of bgp items (anomized of course) ? I don't have any working BGP peers to test.

[bramwittendorp]

Sure, I have identified that the first part is already where the main issue occurs. Currently the code is calling for menu's like: /routing/bgp/peer/print or /routing/bgp/instance/print. These levels don't exist anymore in RouterOSv7.

For example you'll need the /routing/bgp/session/print command to show an overview of the (established) BGP sessions. That's what I am using in the snippet below.

>>> from librouteros import connect
>>> from pprint import pprint
>>> api = connect(
... username='<<redacted>>',
... password='<<redacted>>',
... host='<<redacted>>',
... )
>>>
>>> for row in api('/routing/bgp/session/print'):
...     pprint(row)
...
{'.id': '*2800001',
 'ebgp': '',

I think the main question is: do we want to support both RouterOS v6 and RouterOS v7 in the same version of the driver? I can imagine creating a 2.X release that supports RouterOS 7 but lacks support for RouterOS 6 (which would require 1.X releases).

I am open to contributing to this issue myself, I am not an experienced developer. But I believe in contributing to the community and this might be a useful way to develop my python-skills.

Driver can support both versions. It's just a matter of executing different functions depending on version. tests/unit/mocked_data/test_get_bgp_neighbors/ipv4-only This is a sample mocked data which well mocks real data on device. I can help you develop a patch for v7.x The trick here is to mock data from v7.x and write code that extracts necessary info. You can put mocked data for v7.x into tests/unit/mocked_data/test_get_bgp_neighbors/v7.x/ and write code. file names starting with _ represent command that would be run on mikrotik. _routing_bgp_peer_print.json is equal to /routing/bgp/peer/print in api.
