You have to specify the new list of the blacklisted routes excluding the one you want to drop. For example:
1) updateZoneLevelParameters&zoneId=1&blacklistedRoutes=10.1.1.0/24,10.1.2.0/2 4 2) if you want to drop the last route from the black list, execute: updateZoneLevelParameters&zoneId=1&blacklistedRoutes=10.1.1.0/24 Any zone configuration parameter will be stored as a String, and to update it with the new value, you will have to re-define the string anew. Assuming your next question will be - how to re-set the parameter to Null/empty. For that, refer to Harikrishna Patnala - a developer for "Granular Global Config Parameters" feature. The feature's API should support resetting granular global configs. -Alena.
