Steps to reproduce:

fluorine karaf with ( tested on version 4.11.2018 )

feature:install odl-restconf odl-bgpcep-bgp odl-bgpcep-bgp-config-example

configure peer with local-as, there is config in the file.
```
./conf2.py
```

start exabgp

env exabgp.tcp.port=1790 exabgp --debug default2.cfg

Also reproducable on sandbox with PATCHREFSPEC: refs/changes/41/70841/5
and SUITES: bgpcep/bgpuser/basic.robot

If I configure play.py with --asnumber=64496 for example, it does connect and there is as sequence in loc-rib with 64496 and 65432.
