Abstract:
The procedure to handle host mobility in a layer 2 Network with EVPN
control plane is defined as part of RFC7432. EVPN has since evolved
to find wider applicability across various IRB use cases that include
distributing both MAC and IP reachability via a common EVPN control
plane. MAC Mobility procedures defined in RFC7432 are extensible to
IRB use cases if a fixed 1:1 mapping between host IP and MAC is
assumed across host moves. Generic mobility support for IP and MAC
addresses that allows these bindings to change across moves IS
REQUIRED to support a broader set of EVPN IRB use cases. EVPN all-
active multi-homing further introduces scenarios that require
additional consideration from mobility perspective. This document
enumerates a set of design considerations applicable to mobility
across these EVPN IRB use cases and updates sequence number
assignment procedures defined in RFC7432 to address these IRB use
cases.
NOTE TO IESG (TO BE DELETED BEFORE PUBLISHING): This draft lists six
authors which is above the required limit of five. Given significant
and active contributions to the draft from all six authors over the
course of six years, we would like to request IESG to allow
publication with six authors. Specifically, the three Cisco authors
are the original inventors of these procedures and contributed
heavily to rev 0 draft, most of which is still intact. AT&T is also
a key contributor towards defining the use cases that this document
addresses as well as the proposed solution. Authors from Nokia and
Juniper have further contributed to revisions and discussions
steadily over last six years to enable respective implementations and
a wider adoption.
