Hi @pshemk - thanks for your contribution.

We have thought about this improvement, see https://github.com/napalm-automation/napalm-base/issues/174. Another thing we wanted to tackle is adding a new field inside the output: next_hop_type. Do you think you could do that too? Please note that this is an API change and we'll nee to implement the changes in two more drivers: iosxr and eos.

I've renamed table to 'vrf'. I realise that for consistency we should use vrf, but in junos a vrf can have multiple tables, so this might be a tad confusing too.

What is 'next_hop_type' in this context? It looks like the current implementation pulls out all the route properties already:

            "route_to": {
                "13.107.16.0/24": [
