| | //OLSR has been changed significantly since this article was written, Notably, there is a "v2" that is IETF Standards Track that is described at https://tools.ietf.org/html/rfc7181 and several updates since published in 2014.// |

| Mesh networks self-arrange and auto-configure themselves on the basis of network topology changes. For example, the properly configured OLSR mesh will automatically arrange itself in cases where one node fails, or when a new route emerges, or when a low traffic route becomes available or disappears. The concept of a mesh network is not new; the Internet itself is a huge mesh network. So what's new? Well, mesh networks with wireless technology on OpenWrt simply rocks! ;) | Mesh networks self-arrange and auto-configure themselves on the basis of network topology changes.

| - separate the wireless and lan interface in ''[[docs:user-guide:network:basics|/etc/config/network]]'' again, by default they are bridged | - separate the wireless and lan interface in ''[[docs:guide-user:base-system:basic-networking|/etc/config/network]]'' again, by default they are bridged |

| You may want to check out some of the plugins that are easy to configure and show you the basic status of your mesh. On my network I run ''olsrd-mod-httpinfo'', which provides a basic http server that shows you the status of the mesh. | You may want to check out some of the plugins that are easy to configure and show you the basic status of your mesh.
