ospf segment-routing global block
Use this command to set the Segment Routing Global Block (SRGB) range at each node. The SRGB is the range of labels reserved for segment routing. In MPLS, SRGB is the set of labels reserved for global segments.
SRGB range must be configured as non-overlapping range for each IGP instances and also for each IGP protocols. IGP protocols must use SRGB range within the globally configured SRGB value or default SRGB value if no global SRGB is configured.
Use the no form of this command to remove an SRGB range. Segment routing must be disabled before removing a particular range.
