Description 1
a 'Generic Label' for LDP.
An entry in the 'mplsLdpEntityTable' will only have
associated entries in this Table if Generic Labels
are configured for a specific 'mplsLdpEntityEntry'.
Thus, not every 'mplsLdpEntityEntry' will have
associated entries in this table.
The InterfaceIndex value for a Generic Label is
from the 'ifLayer' where the label is created. Likewise,
the ifType of the interface is the 'ifLayer' where the
label is created. For example, if an implementation
creates the generic label at the ifLayer which
has the 'ifType' of 'mpls', then the
'mplsLdpConfGenericIfIndexOrZero' object
should be set to the value of the InterfaceIndex
for this 'ifLayer'.
If the value of 'mplsLdpConfGenericIfIndexOrZero' is zero
then the InterfaceIndex value of this object is not known.
If this Generic Label is used, i.e. a session has been
established successfully and data is forwarded using this
label, then the value of the
'mplsLdpConfGenericIfIndexOrZero' object MUST be
updated by the network management entity
(e.g. SNMP agent) to reflect the InterfaceIndex
value for the 'ifLayer' that created the Generic Label.
To summarize, not all implementations may assign ifIndices
at a label's creation time, thus, an ifIndex value
may not be known, until a subsequent time. However,
once that ifIndex value is known, the
'mplsLdpConfGenericIfIndexOrZero' object
should be changed to reflect the ifIndex value.
