Dear all,

A new document draft-zl-lsr-igp-sub-interface-relationship-00 has been 
submitted. This draft introduces extensions to IGP, allowing a network device

Abstract:

   This document extends ISIS and OSPF, allowing a network device to
   advertise the relationship between a physical interface and its sub-
   interfaces.  This extension enables the links based on sub-interfaces
   to participate in the alternative paths for load balancing in SRv6 BE
   bandwidth polling.
