Abstract

This document proposes a way to signal Maximum SID Depth (MSD) supported by a node at node and/or link granularity by a BGP-LS speaker. In a Segment Routing (SR) enabled network a centralized controller that programs SR tunnels needs to know the MSD supported by the head-end at node and/or link granularity to push the SID stack of an appropriate depth. MSD is relevant to the head-end of a SR tunnel or Binding-SID anchor node where Binding-SID expansions might result in creation of a new SID stack.
