When requesting a session with resources that are attached by nonnative network type 2.1 connections, the originating LU should specify the NETID of the adjacent node or no NETID. If the originating LU specifies the NETID of the adjacent node, the destination LU must be located in the same network as the adjacent node. If a session request does not include a NETID for the destination LU and a predefined alias CDRSC is defined for the destination LU, the resource can be located in any network.
