 OSPF Segment Routing
 ====================
 
-This is an EXPERIMENTAL support of draft

 * Node MSD configuration (with Linux Kernel >= 4.10 a maximum of 32 labels

 * Automatic provisioning of MPLS table
+* Equal Cost Multi-Path (ECMP)
 * Static route configuration with label stack up to 32 labels
 
 Interoperability

 * Tested on various topology including point-to-point and LAN interfaces

 Note that only prefix of Loopback interface could be configured with a Prefix
 SID. It is possible to add `no-php-flag` at the end of the prefix command to
 disable Penultimate Hop Popping. This advertises to peers that they MUST NOT pop

 * Only single Area is supported. ABR is not yet supported

 * Extended Prefix Range is not supported
