Description: This attribute specifies the list of RIDs whose true reachability is advertised to the instance RID. RIDs which do not appear in this list are advertised to the instance RID as being unreachable from this node.

By default, this list contains all valid RIDs, meaning that true reachability information for all RIDs is advertised to the instance RID.

When this list is empty, all RIDs will be advertised to the instance RID as unreachable, including this node's own RID, therefore the instance RID will not route any RID traffic to this RID. A warning is generated when an empty export list is detected.

RID 127 is the Network Services Sharing (NSS) RID, used to identify DPN-100 nodes running call servers which can be used for remote call processing. This RID can be filtered like any other using the import RID list.
