Again, while there are over 500 gateways in the current network with
tunnels
between all of them, there is no way they are all going to be in use.
It doesn't matter how many are in use. If my ampr routing table has
50 or 500 or 5000 routes, who cares?
That is true for the Linux or JNOS situation. However, people want to use the equipment they have available, and on many other systems there has to be a separate virtual interface for every tunnel. Scripts exist for e.g. MikroTik and Cisco routers that manage this, but they have to create a large number of tunnel interfaces and they hit limits of NVRAM size and others. With 5000 endpoints there will certainly be issues!
Wiring them up for everyone really makes no sense, and introduces a
scalability
problem that would become real when it were easier to use the system
and we had like
50000 participants instead of 500.
Do you have evidence for your statements?
Yes. See above. I also once tried to use a left-over Cisco router and its NVRAM already was too small for this.
https://qrznow.com/us-amateur-radio-population-grows-slightly-in-2018/ It looks like from 2014 to 2018, the US ham population only grew 4%. And I haven't monitored it closely. But it seems to me that the size
of amprnet has remained about the same (+/- 100 or so) for the last 10 years.
So who/where are these 49,500 other gateways?
They probably are either not interested, or they are unable to overcome the problems setting up an IPIP gateway. When we introduced the easier OpenVPN connection method here, there was a flurry of requests for certificates and there now are 200 certificates active. And that is only for one small country.
