*** THIS TABLE CURRENTLY NOT IMPLEMENTED ***
This attribute indicates the throughput link group, or groups, that
are being used to reach a neighbor which is the next hop in the path
to the destination RID. DPN traffic will be spread across the links,
in up to two link groups, when available. The link groups selected
are those associated with the two loop-free paths with the lowest
throughput metrics to the destination.
The link group can be that of either a Passport node interconnection
or a gateway to an RM.
If no link groups are listed then the destination is not reachable in
the throughput class of service (except in the case of the local
node's RID).
Link group instances are managed by the TransportResource
component. Further information about the links in the group can be
obtained from it.
