Dear WG

As requested by the authors, this message starts a two-week WG Last Call for  ending on January 26th 2026.

https://datatracker.ietf.org/doc/draft-ietf-lisp-rfc8378bis/

Title: Signal-Free Locator/ID Separation Protocol (LISP) Multicast

Abstract:
  This document describes the design for inter-domain multicast
   overlays using the Locator/ID Separation Protocol (LISP).  The
   document specifies how LISP multicast overlays operate over a unicast
   underlays.
   When multicast sources and receivers are active at Locator/ID
   Separation Protocol (LISP) sites, the core network is required to use
   native multicast so packets can be delivered from sources to group
   members.  When multicast is not available to connect the multicast
   sites together, a signal-free mechanism can be used to allow traffic
   to flow between sites.  The mechanism within here uses unicast
   replication and encapsulation over the core network for the data
   plane and uses the LISP mapping database system so encapsulators at
   the source LISP multicast site can find decapsulators at the receiver
   LISP multicast sites.  This document when approved obosletes RFC8378.

Please review this WG document and let the WG know if you agree that it is ready to be handed over to the AD.

 If you have objections, please state your reasons why, and explain what it would take to address your concerns.

Note: silence IS NOT consensus.

Thanks

Padma and Luigi
