| Description | A row in this table represents one cross-connect
entry. The following objects index it:
- cross-connect index mplsXCIndex that uniquely
identifies a group of cross-connect entries
- interface index of the in-segment,
mplsInSegmentIfIndex
- incoming label(s), mplsInSegmentLabel
- out-segment index, mplsOutSegmentIndex
Originating LSPs:
These are represented by using the special
combination of values mplsInSegmentIfIndex=0 and
mplsInSegmentLabel=0 as indexes. In this case the
mplsOutSegmentIndex MUST be non-zero.
Terminating LSPs:
These are represented by using the special value
mplsOutSegmentIndex=0 as index.
Special labels:
Entries indexed by reserved MPLS label values 0
through 15 imply terminating LSPs and MUST have
mplsOutSegmentIfIndex = 0. Note that situations
where LSPs are terminated with incoming label equal
to 0, should have mplsInSegmentIfIndex = 0 as well,
but can be distinguished from originating LSPs
because the mplsOutSegmentIfIndex = 0. The
mplsOutSegmentIfIndex MUST only be set to 0 in
cases of terminating LSPs.
An entry can be created by a network administrator
or by an SNMP agent as instructed by an MPLS
signaling protocol. |
