Hi WG,

A new version of I-D, draft-li-idr-sr-policy-path-mtu-02.txt has been successfully submitted. 

This document defines extensions to BGP to distribute path MTU information within SR policies. 
SRv6 packets will be dropped if the packet size is larger than path MTU, since IPv6 packet  cannot be fragmented on transmission [RFC8200] , so PMTU is a very important property of SR policy.

Welcome to review the document. If you have any comments, please let us know. Your comments are always welcome!

Thanks,
Cheng

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.

                                                                                  


Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
