Abstract
Segment routing is a source routing paradigm that explicitly indicates
the forwarding path for packets at the ingress node. An SR policy is a
set of candidate SR paths consisting of one or more segment lists with
necessary path attributes. However, the path maximum transmission unit
(MTU) information for SR path is not available in the SR policy since
the SR does not require signaling. This document defines extensions to
BGP to distribute path MTU information within SR policies.
