QuestionQ187

MPLS and Segment Routing

A network engineer must implement a Segment Routing policy rule that requires SIDs to be manually bounded. The policy will steer traffic based on incoming labeled traffic using binding SIDs, adjacency SIDs, and BGP peering SIDs. All labels will reside in the local segment, within the range of 40000 to 50000. How must the engineer implement dynamic label allocation?

  • A Implement a non-default SRLB range in the SR global segment.
  • B Implement the standard default SRGB range in the SR global segment.
  • C Implement a non-default SRGB range in the SR local segment.
  • D Implement the default SRLB range in the SR local segment.
Explanation

Binding SIDs, adjacency SIDs, and BGP peering SIDs are local segments that use the SRLB. Because the default SRLB is 15000–15999, labels in the 40000–50000 range require a non-default SRLB, configured in global Segment Routing configuration mode.
