This document proposes a way to expose Maximum SID Depth (MSD) supported by a node at node and/or link level by an OSPF Router. In a Segment Routing (SR) enabled network a centralized controller that programs SR tunnels at the head-end node needs to know the MSD information at node level and/or link level to push the label stack of an appropriate depth . Here the term OSPF means both OSPFv2 and OSPFv3.
