                      This sum initially takes the value zero.  For each
                      version, V, that this interface supports, 2 raised
                      to (V - 1) is added to the sum. For example, a
                      port supporting versions 1 and 2 would have a
                      value of (2^(1-1)+2^(2-1))=3.  The
                      sipL3VersionSupport is effectively a bit mask with
