MPLS-FRR-FACILITY-STD-MIB Table View

The mplsFrrFacilityDBTable provides information about the
fast-reroute database.  Each entry belongs to a protected
          
interface, protecting backup tunnel, and protected tunnel.
MPLS interfaces defined on this node are protected by
backup tunnels and are indicated by the index
mplsFrrFacilityProtectedIfIndex.  If the interface index is
set to 0, this indicates that the remaining indexes apply
to all configured protected interfaces.
          
Note that all objects in this table are read-only, and
if new objects are added to this table, they should also
be read-only.
          
It is recommended that ifIndex persistence be enabled
across re-initializations.
If persistence is not implemented, then the value of
mplsFrrFacilityProtectedIfIndex in this
table cannot be guaranteed across restarts and all entries
in this table MUST NOT be persistent, or the values of
mplsFrrFacilityProtectedIfIndex MUST be reconstructed
on restart.
          
It is recommended that entries in this table be persistent
across reboots.
          
The protecting tunnel is indicated by the
index mplsFrrFacilityProtectingTunnelIndex and
represents a valid mplsTunnelEntry.  Note that the tunnel
instance index of the protecting tunnel may be set to 0,
which indicates the tunnel head interface for the
protecting tunnel, as per RFC 3812, but it may also be
defined using the following semantics:
          
- lower 16 bits : protected tunnel instance
- higher 16 bits: must be all zeros
