DON'T use it for production network.
Supported Features
------------------
* Automatic computation of Primary and Backup Adjacency SID with
Cisco experimental remote IP address
* SRGB configuration
* Prefix configuration for Node SID with optional NO-PHP flag (Linux
kernel support both mode)
* Node MSD configuration (with Linux Kernel >= 4.10 a maximum of 32 labels
could be stack)
* Automatic provisioning of MPLS table
* Static route configuration with label stack up to 32 labels
Interoperability
----------------
* Tested on various topology including point-to-point and LAN interfaces
in a mix of Free Range Routing instance and Cisco IOS-XR 6.0.x
* Check OSPF LSA conformity with latest wireshark release 2.5.0-rc
Implementation details

* MPLS table are not flush at startup. Thus, restarting zebra process is
mandatory to remove old MPLS entries in the data plane after a crash of
ospfd daemon
* Due to a bug in OSPF Opaque, LSA are not flood when enable Segment Routing
through CLI once OSPFd started. You must configure Segment Routing within
configuration file before launching OSPFd
* With NO Penultimate Hop Popping, it is not possible to express a Segment
Path with an Adjacency SID due to the impossibility for the Linux Kernel to
perform double POP instruction.
