Attribute 0x11 on the Bridge Basic Info cluster is Reachable.

The Reachable attribute SHALL be used to indicate whether the bridged device is reachable by the bridge over the non-Matter network, so a Matter Node which wants to communicate with a bridged device can get an indication that this might fail (when the attribute is False). Determination of reachability MAY not be perfect (e.g. depending on technology employed), so the Matter Node SHOULD be aware of the risk of false positives and negatives on reachability determination. For example, a bridged device MAY be marked as unreachable while it could actually be reached, and vice-versa.

9.13.5.2. ReachableChanged Event This event SHALL be generated when there is a change in the Reachable attribute. Its purpose is to provide an indication towards interested parties that the reachability of a bridged device (over the non-Matter network) has changed, so they MAY take appropriate action. After (re)start of a bridge this event MAY be generated.
