Hi All,<br><br>I realize that Henning's draft proposal for the LDEP (quoted below) would effectively address the need I describe, but I am curious about existing methods available for bridging multiple radios/APs to operate on the same logical mesh.<br>
<pre> "Stateless RFC5444-based Dynamic Link Exchange Protocol (DLEP)", Henning
Rogge, 4-Nov-12, <draft-rogge-stateless-rfc5444-dlep-00.txt>
This document provides material for the discussion in the MANET WG
about the Dynamic Link Exchange Protocol (DLEP). This document
reflects the authors' thoughts about how a stateless DLEP protocol
compliant with RFC5444 could look like.
</pre>Because UBNT radios can be quite flexible about how (and more poignantly how many) you strap them to a mast with minimal cabling, cf. their <a href="http://wiki.ubnt.com/BeansTalk_PoE_bridge">Beanstalk illustrations</a>, I am curious about wired bridging options between multiple APs, and what such options can do to reduce hop loss and/or allow meshing on multiple channels.<br>
<br>That is, if you could connect the LAN ports of two radios together, could you ...<br><br>1. Mount the radios on the same mast, but facing 180deg away from each other (assuming directional antennas), to join two meshes that otherwise don't overlap? This neglects interference from overlapping fresnel zones, but there are <a href="http://www.rfarmor.com/cart/index.php?main_page=index&cPath=12">means</a> to mitigate interference.<br>
<br>2. Same #1, but imagine now the meshes overlap geographically, yet operate on different channels?<br><br>Since OLSRd could be (or is) quite capable of routing across hybrid topologies like these, and since zealous IPv6 addressing of all nodes could eliminate awkward NAT schemes, I'm curious about options for building efficient bridges between two APs. Especially, I'd be curious to hear what other OLSRers have done. How have you seen SmartGateway operate over such topologies, for example?<br>
<br>OpenWRT has Layer 3 tools like relayd, but there is also a simpler tool call trelay, which looks appealing:<br><a href="https://dev.openwrt.org/browser/trunk/package/trelay/Makefile">https://dev.openwrt.org/browser/trunk/package/trelay/Makefile</a><br>
