Title : Adjacency Reduction in OSPF using SPT Reachability
Author(s) : A. Roy
Filename : draft-roy-ospf-smart-peering-00.txt

There is a significant overhead in OSPF if a router has to establish
adjacencies with every peer it can verify 2-way connectivity with.
OSPF supports a broadcast network type for these scenarios, where you
only have to peer with a designated router (DR). But a full mesh of
connectivity is required for proper DR election, so this doesn't help
in networks with overlapping partial meshes of connectivity. This
draft proposes a technique to reduce the number of adjacencies based
on the shortest path tree (SPT) reachability information.

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.
