Abstract:
   Instead of forwarding to a specific device or to all devices in a
   group, anycast addresses, let network devices forward a packet to (or
   steer it through) one or more topologically nearest devices in a
   specific group of network devices.  The use of anycast addresses has
   been extended to the Segment Routing (SR) network, wherein a group of
   SR-capable devices can represent a anycast address, by having the
   same Segment Routing Global Block (SRGB) provisioned on all the
   devices and each one of them advertising the same anycast prefix
   segment (or Anycast SID).

   This document describes a proposal for implementing anycast prefix
   segments in a MPLS-based SR network, without the need to have the
   same SRGB block (label ranges) provisioned across all the member
   devices in the group.  Each node can be provisioned with a separate
   SRGB from the label range supported by the specfic hardware platform.
