+ A router port is always attached to a logical switch and to a logical
+ router. The former attachment, which is enforced by the database schema,
+ can be identified by finding the <ref table="Logical_Switch"/> row whose
+ <ref column="router_port" table="Logical_Switch"/> column points to the
+ router port. The latter attachment, which the database schema does not
+ enforce, can be identified by finding the <ref table="Logical_Router"/>
+ row whose <ref column="ports" table="Logical_Router"/> column includes
+ the router port.
