Exchange of routing information between IPsec security gateways,
using standard routing protocols across IPsec tunnels, can be a
straightforward operation. Using the routing information to choose
the proper path is also straightforward, when routing is
functionally separated from the IPsec gateway operation. One of the
most significant obstacles to widespread implementation of dynamic
routing in IPsec VPNs has been agreement on a way to unambiguously
signal the capability of the gateways to exchange and use the
routing information. This document describes a simple and secure
method of signaling this capability and exchanging dynamic routing
information between IPsec security gateways, using standard IPsec
messages. This method is currently in use in a large number of
installations.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
