LISP Mapping Bulk Retrieval
draft-boucadair-lisp-bulk-05
Abstract
This document extends Locator/ID Separation Protocol (LISP) with a
capability for bulk mapping retrieval. It does so by defining new
LISP messages that are meant to facilitate state recovery of mapping
tables and improve Ingress Tunnel Routers (ITR) recovery times, in
particular. In addition, this document allows to request mappings
that match destination IP prefixes, names, or AS numbers.
This document updates RFC6830.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].

1. Introduction
Locator/ID Separation Protocol (LISP, [RFC6830] ) operation relies
upon a mapping mechanism that is used by ingress/egress Tunnel
Routers (xTR) to forward traffic over the LISP network. This
document extends LISP with a capability for bulk mappings retrieval.
It does so by defining new LISP messages that are meant to facilitate
state recovery of mapping tables and improve Ingress Tunnel Routers
(ITR) recovery times, in particular.
The base LISP specification does not define how a requestor may ask
for multiple EIDs. Indeed, the current LISP specification [RFC6830]
states the following:
