Abstract: This document is a complete replacement of the previous versions by the same title. Customer experience with the zBX has led IBM to depart from its original requirements for Layer-3 connectivity between the external data network and the IEDN TORs of the zBX. Test cases show that IBM can support a wider set of connectivity alternatives than those that were originally recommended. As long as a customer follows a minimum set of rules for connectivity to the zBX, the attachment to the external ports of the zBX can be implemented with either Layer-3 or Layer-2 definitions.
