Hi,

draft-ietf-mpls-lsr-mib-07 describes NHLFE as three separated entries:
MplsInSegmentEntry, MplsOutSegmentEntry and
MplsXCEntry. Both MplsInSegmentEntry and MplsOutSegmentEntry are
pointing to MplsXCEntry.
I assume this structure is needed in order to support point-to-point,
point-to-multipoint and multipoint-to-point connections
at an LSR.
Does supporting point-to-multipoint mean MPLS-multicasting ?
Is this structure of NHLFE needed to support mpls-multicasting (as
describes in draft-ietf-mpls-multicast-05) ?

What about LSR's that have no support for mpls-multicasting, handling
such a structure for NHLFE might be useless and
inefficient ?

Regards, Lior.
