+Manage IP addresses with bridge status
+======================================
+
+[◀ Go back to main README](../README.md)
+
+Description
+-----------
+
+With RouterOS an IP address is always active, even if an interface is down.
+Other venders handle this differently - and sometimes this behavior is
+expected. This script mimics this behavior.
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate ip-addr-bridge;
+
+... and make it run from scheduler:
+
+    / system scheduler add name=ip-addr-bridge on-event="/ system script run ip-addr-bridge;" start-time=startup;
+
+This will disable IP addresses on bridges without at lease one running port.
+The IP address is enabled if at least one port is running.
+
+Note that IP addresses on bridges without a single port (acting as loopback
+interface) are ignored.
