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.
