When you restart the bgp routing protocol via "restart bgp"
it throws an error that the route-maps do not exist.
I was able to reproduce this in any configuration where a route-map is used in a BGP neighbour configuration.
The BGP session then will be established **WITHOUT** any filters and produces route leaks.
```

The route-map 'INT-RS-IN' does not exist.
The route-map 'INT-RS-OUT' does not exist.
