 For each neighbor of the queried multicast router, the IP of the queried router
 is displayed, followed by the IP and name of the neighbor. In square brackets
-the metric (cost of connection), the treashold (multicast ttl) is displayed. If
+the metric (cost of connection), the threshold (multicast ttl) is displayed. If
 the queried multicast router has a newer version number, the type (tunnel,
 srcrt) and status (disabled, down) of the connection is displayed.
