Abstract:
Segment Routing (SR) is a new MPLS paradigm in which each SR-capable
router is required to advertise global MPLS labels or Segment IDs
(SID) for its attached prefixes by using link-state IGPs, e.g., OSPF.
One major challenge associated with such global MPLS label or SID
advertisement mechanism is how to avoid a given global MPLS label or
SID from being allocated by different routers to different prefixes.
Although such global label or SID allocation collision problem can be
addressed through manual allocation , it is error-prone and
nonautomatic therefore may not be suitable in large-scale SR network
environments. This document proposes an alternative approach for
allocating and advertising global MPLS labels or SIDs via OSPF so as
to eliminate the potential risk of label allocation collision.
