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. [I-D.ietf-spring-segment-routing]
extended the use of anycast addresses to a SPRING network, wherein a
group of SPRING-capable devices can represent a anycast address, by
having the same SRGB label block 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 SPRING, 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.
