    Protocol version ID Description

    6.0.2.9 This version was included in the V6.0.2.9 service pack to facilitate core group bridge scalability. This version is recommended for large topologies that contain multiple core groups and core group bridges as part of their configuration.
    6.1.0 This version was included in V6.1 to add core group scalability improvements, and more support for large topologies.
