The operands on this PATH definition statement are the same as those on VTAM routes, with one exception. If the SSCPNAME on the VPATH definition statement matches VTAM®'s, the values of the destination subarea and adjacent subareas used in the PATH definition statement must not exceed the subarea addressing supported by the SSCP (as defined by the MXSUBNUM start option).
Code the VPATH definition statement to identify the VTAM subarea and the network to which the path update specification set applies in a dynamic path update member. This definition statement is required and must precede the path update specifications for each subarea. The VPATH definition statement is not allowed in the path definition set.
