Very nice feature and from my first impression it works really well!
What I have noticed so far:
1. if you remove interfaces from a node in OSPF you can't add them later 
and if you remove the last one you get the following error:

```
Parameter verification failed. (400)
*interfaces*: type check ('array') failed
```

which could be turned into a nicer message or even allowed (why can i 
not remove all interfaces for maintenance reasons?).

2. is there a use-case where i do not want to use an interface 
`unnumbered` nor with an ip address?
If you also can't think of any i'd suggest restricting it so that the 
user has to either tick `unnumbered` or enter an ip address.
I think this would help users starting with OSPF, configuring a node and 
wondering why it is not working.
