The neighbors/$ID/routes endpoint returns "not_exported" routes for neighbors with different ID

[vgiotsas]

When querying the routes of a neighbor with a specific ID the response may contain "not_exported" routes from neighbors with a different neighbor ID. For instance, consider the following query:

https://lg.ecix.net/api/routeservers/0/neighbours/ID481_AS6805/routes

The output is (you can view it formated here):

If I understand correctly, the not_exported routes should only pertain to the queried neighbor.

Hey!

Thanks for the issue! So the no_export should show what routes were not exported TO that peer, so you would expect that the routes were sent by different peers.

We did however notice that your url did contains non_exported routes, but on the peer page: https://lg.ecix.net/alice/routeservers/0/protocols/ID481_AS6805/routes

There is nothing... so there is something fishy going on there.
