Note:
The behavior and limitations of the implementation of the objects in
follows.
The following features are not supported on the 7705 SAR:

• The PCE treats all supported objects received in a PCReq message as
mandatory, regardless of whether the P-flag in the object's common header is
set (mandatory object) or not (optional object).
• The PCC implementation will always set the B-flag (B=1) in the metric object
containing the hop metric value, which means that a bound value must be
included in PCReq message. The PCE returns the computed value in the
PCRep message with flags set identically to the PCReq message.
• The PCC implementation will always set flags B=0 and C=1 in the metric object
for the IGP or TE metric values in the PCReq message. This means that the
request is to optimize (minimize) the metric without providing a bound value. The
PCE returns the computed value in the PCRep message with flags set
identically to the PCReq message.
• The IRO and LOAD-BALANCING objects are not part of the NSP PCE feature.
If the PCE receives a PCReq message with one or more of these objects, it will
ignore them regardless of the setting of the P-flag, and will process the path
computations normally.
• The LSPA, metric, and bandwidth objects are also included in the PCRpt
message. The inclusion of these objects in the PCRpt message is proprietary to
Nokia.
• PCE discovery using IS-IS, per RFC 5089, and OSPF, per RFC 5088, along with
corresponding extensions for discovering stateful PCE, per draft-sivabalan-pce-
disco-stateful
• security of the PCEP session using MD5 or TLS between PCEP peers
• PCEP synchronization optimization as per draft-ietf-pce-stateful-sync-
optimizations
