Comment 1 for bug 1273864

I found the cause of this issues.
It looks like there isn't timing issue.

The route cause of this issue is this bug report.

The script create and deletes networks with same name.
Since contrail data sync model is async and they are using name as a identifier, this won't work
sometimes.

After I update the script to change the name everytime, it starts working.
