Negotiation for Keying Pairwise Routing Protocols in IKEv2
draft-mahesh-karp-rkmp-06
Abstract
This document describes a mechanism to secure the routing protocols
which use unicast to transport their signaling messages. Most of
such routing protocols are TCP-based (e.g., BGP and LDP), and the TCP
Authentication Option (TCP-AO) is primarily employed for securing the
signaling messages of these routing protocols. There are also two
exceptions: BFD which is over UDP or MPLS, and RSVP-TE which is over
IP (but employs an integrated approach to protecting the signaling
messages instead of using IPsec). The proposed mechanism secures
pairwise TCP-based Routing Protocol (RP) associations, BFD
associations and RSVP-TE associations using the IKEv2 Key Management
Protocol (KMP) integrated with TCP-AO, BFD, and RSVP-TE respectively.
Included are extensions to IKEv2 and its Security Associations to
enable its key negotiation to support TCP-AO, BFD, and RSVP-TE.

Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
