Classification: CPC H | IPC H

Claim 12:
13. The system of claim 8, wherein the node label for the first router comprises a first node label for the first router, wherein the flexible-algorithm comprises a first flexible-algorithm, wherein the first router, the second router, the first area border router, and the second area border router participate in a second flexible-algorithm, wherein the label stack comprises a first label stack, wherein the packet comprises a first packet, wherein the second router is further configured to:
receive a second packet destined for the first router;
deduce a second node label, for the first router, associated with a segment routing path computed with the second flexible-algorithm, wherein the segment routing path computed with the second flexible-algorithm is a constraint-based path; and
construct a second label stack including the second node label for the first router to steer the second packet to the first router along the segment routing path computed with the second flexible-algorithm.
