 PCEP Support
 ============
 
-To build the PCC for pathd, the externall library `pceplib 1.2 <https://github.com/volta-networks/pceplib/tree/devel-1.2>`_ is required.
+A pceplib is included in the frr source tree and build by default.
 
-To build FRR with support for PCEP the following steps must be followed:
-
- - Checkout and build pceplib:
-
-```
-$ git clone https://github.com/volta-networks/pceplib
-$ cd pceplib
-$ make
-$ make install
-$ export PCEPLIB_ROOT=$PWD
-```
-
- - Configure FRR with the extra parameters:
-
-```
---enable-pcep LDFLAGS="-L${PCEPLIB_ROOT}/install/lib" CPPFLAGS="-I${PCEPLIB_ROOT}/install/include"
-```
 
 To start pathd with pcep support the extra parameter `-M pathd_pcep` should be
 passed to the pathd daemon.
