Yep! Ground routing is a way of building supernodes developed by ninux community network, in practice because they was experiencing bugs in openwrt drivers and their links were mostly AP-STA they started to separate routing from the radio layer, so on the roof you have CPE that only do radio stuff either with openwrt or fabric firmware, while the router is inside your house, there are two variants, one in which an ethernet cable run from each CPE to the router and one in witch you have a gigabit siwtch on the roof where all CPE are connected and only one gigait ethernet cable run to your ground router, lime actually supports both modes, first mode have the advantage that doesn't needs 802.1q tagged vlan support (on both GR and CPE) while have the disadvantage that you have to run one cable for each CPE, the second mode have the advantage that you can run just one gigabit ethernet cable from your roof switch to your GR but needs that both GR and CPEs have 802.1q tagged vlan support to avoid L2 loop, i believe it have some similaruty with guifi hibrid mode, but using open source router, having now libre-mesh supporting GR it means that supernode configuracion is quite simpler having most of them automatically generated by lime :) A tipical topology with gigabit switch on the roof === ethernet link ------- wireless link In the house 1 on the roof 1 <lime GR 1>======<GbEth switch>||=====<CPE1.1>------ _||=====<CPE1.2>---- _||=====<CPE1.3>---- on the roof 2 In the house 2 --------<CPE2.1>====||<GbEth switch>====<lime GR2> --------<CPE2.3>====|| --------<CPE2.7>====|| --------<CPE2.x>====|| on the roof 3 In the house 2 --------<CPE3.1>====||<GbEth switch>====<lime GR2> --------<CPE3.2>====|| --------<CPE3.y>====|| The usage of tagged 802.1q vlans avoid L2 loop Here you can find more informations about GR https://docs.google.com/document/d/1tEp4rFNDis4RAwwo4wwg6xDMdqeJKAi8FVYh_FsPEdk/edit?pli=1#heading=h.8c5qdfnyo0u7 _______________________________________________ Wireless mailing list Wireless@ml.ninux.org http://ml.ninux.org/mailman/listinfo/wireless
