def get_route_to(self, destination="<STR_LIT>", protocol="<STR_LIT>"):
raise NotImplementedError<EOL>
Returns a dictionary of dictionaries containing details of all available routes to a
destination.

:param destination: The destination prefix to be used when filtering the routes.
:param protocol (optional): Retrieve the routes only for a specific protocol.

Each inner dictionary contains the following fields:

    * protocol (string)
    * current_active (True/False)
    * last_active (True/False)
    * age (int)
    * next_hop (string)
    * outgoing_interface (string)
    * selected_next_hop (True/False)
    * preference (int)
    * inactive_reason (string)
    * routing_table (string)
    * protocol_attributes (dictionary)

protocol_attributes is a dictionary with protocol-specific information, as follows:

- BGP
    * local_as (int)
    * remote_as (int)
    * peer_id (string)
    * as_path (string)
    * communities (list)
    * local_preference (int)
    * preference2 (int)
    * metric (int)
    * metric2 (int)
- ISIS:
    * level (int)
