Comment 3 for bug 1673911

The issues got resolved when I installed the `exabgp` from Github. Before, I used `exabgp` from `pip install`.

```
cd ~ && git clone https://github.com/Exa-Networks/exabgp.git
cd ~/exabgp && git log

    Merge pull request #587 from aj-gh/healthcheck-dynip-fix

    healthcheck.py: Fix nonexistent option name - ips_deleted vs. ip_dynamic
```

Finally:

```
cd ~/exabgp && python setup.py install
```

Now, no failures:

```
# bagpipe-bgp --version
bagpipe-bgp 6.0.1.dev68
#
```
