 between three separate listener interfaces which each listen for three of the
 nine events. Here are the three interfaces and the events they listen for:
 
-- ``ClusterListener``: :spec:`topology </server-discovery-and-monitoring/server-discovery-and-monitoring.rst#topology>`
-  related events
+- ``ClusterListener``: topology-related events
 - ``ServerListener``: events related to ``mongod`` or ``mongos`` processes
 - ``ServerMonitorListener``: heartbeat related events
 
 To monitor a type of SDAM event, write a class that
 implements one of the three preceding interfaces and register an instance of that
 class with your ``MongoClient`` instance.
