I don't think that's even HD. :( Here in Green Bay, WI a few of us have been messing with point to point 802.11 since 1999. Sadly there isn't enough interest (mostly due to the average ham club members age I suspect), for it to advance much beyond that... so far. Although I have finally pulled some strings for commercial tower space come spring. Without one end up high (above the average 100 foot trees), you need amplifiers to go anywhere, or a MESH node every couple miles? So far I have not done anything with Mesh, and it sort of makes sense for the distance/propagation delima.. Till I think, wait a second, 802.11 is still half duplex, so when you make a (metric) hop using a mesh topology, aren't you effectively cutting your bandwidth in half? So there is more to this than throw a bunch of nodes out there. (bandwidth and hidden transmitter stuff), there is just no easy way around a decently designed network.. backbones! Then there is the oh, well we want to expand the network this way (something not in the original plan), and how to make the subnet and routes all work, short of re-addressing everything. I watched the HamWAN DCC video.. and I have often thought about 5 GHz Mikrotik Groove as they way I'd go if I were to invest in equipment again. More so, if bouncing off say a water tower actually is doable. Steve, KB9MWR

This. So this is how I'd see it work, I need to write up a proposal for it. You have regional BGP routers that route subnets to the internet. These could then tunnel the subnets to end users via GRE. End users could route via an IGP over this tunnel to the regional speaker(s). Multiple tunnels would give redundancy. The regional speakers would have a tunnel between them. In the event of an outage the other BGP speakers would route subnets. Multiple links from end users to other BGP speakers (or non-speakers that are aggravation routers) would provide redundancy to the end users. Of course nothing prevents having a direct BGP speaker with an RF link to end users, most data centers will not have roof rights however. We could setup redistribution that would pull announcements from BGP if end nodes went down. Each BGP speaker could announce the subnets it knows about and a /8 providing we have a mesh of the backbone bgp speakers.

[nos-bbs] strange udp broadcasts...
by Nigel Vander Houwen 31 Jan '14

31 Jan '14

First, apologies for this email not being a valid reply. Finally got around to getting on the mailing list, so I haven't gotten the previous thread to reply to. I've adjusted our scripting that generates our AMPR tunnels on the HamWAN edge routers to disable neighbor discovery for those interfaces, and the change should now be in effect. Thanks, Nigel K7NVH

Getting mikrotik router gateway connected to amprgw
by Ryan Elliott Turner 30 Jan '14

30 Jan '14

Hi list, I'm trying to get a mikrotik RB2011 connected to AMPRGW but not having success. /ip route check 44.0.0.1 status: ok interface: ampr-gw nexthop: 44.0.0.1 /tool traceroute 44.0.0.1 # ADDRESS LOSS SENT LAST AVG BEST WORST STD-DEV STATUS 1 44.34.128.1 0% 2 0.5ms 0.5 0.5 0.5 0 host unreachable from 44.34.128.1 2 0% 0 0ms Using the sniffer, I've tried to also ping my address (44.34.128.1) from the outside, but it does not get through. In addition, pinging 44.0.0.1 from the router fails as well (tracert shown above). I do however see a discovery attempt going out and not getting any response back. /tool sniffer quick interface=ampr-gw INTERFACE TIME NUM DIR SRC-MAC DST-MAC VLAN SRC-ADDRESS DST-ADDRESS PROTOCOL SIZE ampr-gw 33.3 1 -> 44.34.128.1:5678 (discovery) 255.255.255.255:5678 (discovery) ip:udp 114 I do have an IPIP interface to the edge router for 44.24.240.0/20, and that is operating properly; I can access their network, and they can access mine. So, I'm a bit puzzled by this. My config amprgw: /interface ipip add local-address=99.173.137.24 name=ampr-gw remote-address=169.228.66.251 /ip route add distance=1 dst-address=44.0.0.0/8 gateway=ampr-gw Any help is greatly appreciated! -- Ryan Turner

This, i've got it going, but requiring a mesh of tunnels is nasty and it's hard to maintain (absent custom protocols) As it stands now, my BGP space can talk to the rest of the internet, but no other 44/8 (excluding the 9 BGP subnets). I'd love to write up an draft proposal for AMPRnet on how to fix this, but I just don't have the time right now. I'd want it as a standard that works on all routers at least for the "core". Perhaps even a route reflector software would work (ALU/CSCO/JNPR have this now). Even foundcade would work, the MLX's don't shit the bed anymore :) Mikrotik is not something you can put in a CO/datacenter for obvious reasons. I'd love to say we need a custom protocol, but the chances of getting that supported on anything production grade is slim to none. Argh, I'll have to make time to do this. I travel about 75% of the time for work, it sucks. I'm a bit hungover in an airport now even :) 73's -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

It's just a subnet for gods sake - stop playing with it and route the shit already, then we might actually get to DO SOMETHING over it. Puhleeease.. >

is there a written spec for exactly what the amprnet portal needs to do and keep track of? Might it be available for review and reading? Thanks, Eric Fort AF6EP
