Approach

What is the motivation for this PR?

We need to deploy a new T0 LAG topology with 8 up links (LAGs) in the lab - 2 ports per LAG.

How did you do it?

Created a new T0 topo yml file, as well as a leaf template for the 8 EOS uplinks.

How did you verify/test it?

Ran add-topo successfully on a Mellanox SN2700 using ceos, and all 8 uplinks come up with bgp connections paired successfully.

The pre-commit check detected issues in the files touched by this pull request.
The detected issues may be old or new. For new issues, please try to fix them.

For old issues, it is not mandatory to fix them because they were not caused by this change. It is unfair to blame
author of this pull request. But if you can take extra effort to fix the old issues as well, that would be great!

To run the pre-commit checks locally, you can follow below steps:

1. Ensure that default python is python3. In sonic-mgmt docker container, default python is python2. You can run
   the check by activating the python3 virtual environment in sonic-mgmt docker container or outside of sonic-mgmt
   docker container.
2. Ensure that the pre-commit package is installed:

sudo pip install pre-commit

3. Go to repository root folder
4. Install the pre-commit hooks:

pre-commit install

5. Use pre-commit to check staged file:

pre-commit

6. Alternatively, you can check committed files using:

pre-commit run --from-ref <commit_id> --to-ref <commit_id>
