Abstract:
Segment Routing (SR) [SR-ARCH] is a new MPLS paradigm in which each
SR-capable router is required to independently advertise global MPLS
labels for its attached prefixes using IGP [SR-ISIS-EXT][SR-OSPF-EXT].
One major challenge associated with such label advertisement
mechanism is how to avoid a given global MPLS label from being
allocated by different routers to different prefixes. Although manual
allocation can address such label allocation collision problem, it is
error-prone and therefore may not be suitable for large SR network
environments. This document proposes an alternative approach for
advertising global labels without any risk of label allocation
collision.
