Computation Client (PCC). It also shows how to configure the Path Computation Element
Protocol (PCEP) on the PCC to enable PCE to PCC communication.

Requirements
This example uses the following hardware and software components:
Three routers that can be a combination of ACX Series routers, M Series Multiservice
Edge Routers, MX Series 3D Universal Edge Routers, T Series Core Routers, or PTX
Series Transport Router, one of which is configured as a PCC.
A TCP connection to an external stateful PCE from the PCC.
Junos OS Release 12.3 or later running on the PCC along with the JSDN add-on package.
NOTE: The JSDN add-on package is required to be installed along with the
core Junos OS installation package.
Before you begin:
Configure the device interfaces.
1.
Configure MPLS and RSVP-TE.
2.
Configure IS-IS or any other IGP protocol.

Overview
Starting with Junos OS Release 12.3, the MPLS RSVP-TE functionality is extended to
provide a partial client-side implementation of the stateful PCE architecture
(draft-ietf-pce-stateful-pce) on a PCC.
NOTE: The partial client-side implementation of the stateful PCE architecture
is based on version 2 of Internet draft draft-ietf-pce-stateful-pce. Starting
with Junos OS Release 16.1, this implementation is upgraded to support
version 7, as defined in Internet draft draft-ietf-pce-stateful-pce-07. Releases
prior to 16.1 support the older version of the PCE draft, causing interoperability
issues between a PCC running a previous release and a stateful PCE server
that adheres to Internet draft draft-ietf-pce-stateful-pce-07.
