Networks

This document describes the Interzone Routing Protocol (IERP), the
reactive routing component of the Zone Routing Protocol (ZRP).
IERP adapts existing reactive routing protocol implementations to
take advantage of the known topology of each node's surrounding
r-hop neighborhood (routing zone), provided by the Intrazone
Routing Protocol (IARP). The availability of routing zone routes
allows IERP to suppress route queries for local destinations.
When a global route discovery is required, the routing zone based
bordercast service can be used to efficiently guide route queries
outward, rather than blindly relaying queries from neighbor to
neighbor. Once a route has been discovered, IERP can use routing
zones to automatically redirect data around failed links.
Similarly, suboptimal route segments can be identified and traffic
re-routed along shorter paths.

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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
