DESCRIPTION
|

"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"
