statements:

CDRM

dependencies:

VRTG=YES coded; APPN only

Specifies that the virtual-route-based transmission group represents a connection to an interchange node or a migration data host. When this parameter is specified, the network capabilities specified by the adjacent CP during VR-based transmission group activation are validated against the coded value. If the indicators do not match, both the VR-based transmission group and SSCP-SSCP session will be terminated.

When this operand is not specified, no network capabilities are validated.

NN=YES: Indicates that the adjacent node must be an interchange network node.
NN=NO: Indicates that the adjacent node must be a migration data host.

Restriction: In a peripheral subnetwork boundary configuration between a border node and a network node without border node function, the border node appears to the non-border node as an end node. In this case, coding NN=YES on the definition statement that represents the border node, a connection failure will occur. Avoid the failure by not coding the NN operand or by coding NN=NO.
