mplsFrrGeneralConstraintsEntry

An entry in this table represents detour LSP or bypass
tunnel setup constraints for an interface or link to be
protected by detour LSPs or a bypass tunnel.
            
Once the LSP or tunnel instance to be protected is identified
in the mplsTunnelTable, the corresponding mplsTunnelIfIndex
            
value of that tunnel can be used to get the ifIndex of
the underlying physical interface using the ifStackTable.
That ifIndex of the underlying physical interface will
be used as mplsFrrGeneralConstraintsIfIndexOrZero in this
table to protect the LSPs or tunnel instances determined
earlier.
            
It is recommended that ifIndex persistence be enabled
across re-initializations.  If persistence is not
implemented, then the value of
mplsFrrGeneralConstraintsIfIndexOrZero in this
table cannot be guaranteed across restarts and all entries
in this table MUST NOT be persistent, or the values of
mplsFrrGeneralConstraintsIfIndexOrZero MUST be reconstructed
on restart.
            
SNMP engines must only allow entries in this table
to be created for tunnel instances that require fast reroute
as indicated by the presence of the FAST_REROUTE object
in the signaling for the LSP in question.
            
An entry in this table can be created only if a
corresponding entry in mplsTunnelTable exists with the
same mplsTunnelIndex as mplsFrrGeneralConstraintsTunnelIndex.
            
Entries in this table are deleted when the corresponding
entries in mplsTunnelTable are deleted.
            
It is recommended that entries in this table be persistent
across reboots.
            
Entries indexed with mplsFrrGeneralConstraintsIfIndexOrZero
and set to 0 apply to all interfaces on this device for
which the FRR feature can operate.
            
If the mplsTunnelInstance object is set to a value of 0,
it indicates that the mplsTunnelEntry contains a tunnel
ingress.  This is typically how configuration of this
feature is performed on devices where the actual
protection LSP used is left up to the protecting tunnel.
However, in cases where static configuration is
possible, any valid tunnel instance is possible;
however, it is strongly RECOMMENDED that the instance
index SHOULD use the following convention to identify
backup LSPs:
            
- lower 16 bits : protected tunnel instance
- higher 16 bits: must be all zeros
