Hello!

We have WAN consisting of several small nodes linked together with long distance radiolinks (...it's not wi-fi). We bought several MTs RB450 and now we want to restructure our netwrok.
Due to nature of radio, area topography and weather condition our network have some kind of instability: some radiolinks may become unstable or even disappear. So we plan to transform our network into a mesh network with band shaping, dynamic routing, i.e. more failure safe structure.
Here is the image of the simplified plan, which describes our idea. Pls, see the attachment below.

There are two address spaces: the address of entire network is 10.1.0.0/16 (private space), and it's subneted to smaller networks like 10.1.1.0/24, 10.1.2.0/24, etc ...
There is another address space, which is Public address space (Internet accessible), let's say it is like: 11.22.33.0/24 -- these IPs are for end points (clients) of the network. We can not waste these IPs to build internal structure of our network.
As for dynamic routing and failover redundancy, I guess I need to deal with OSPF, configuring MTs with private IP space. The same (OSPF) goes to deal with the task of calculating optimal route using fastest links. Am I right?
I would highly appreciate any ideas for the following:
How to make these end points with Public IPs Internet accessible? Me, I guess I need to deal here with some kind or route discovering protocols (RDP). Am I right? ...Or your ideas?
And finally, how to enable the band shaping?

Any ideas or just links to good source of particular info or documented examples, documentation, etc.. are welcome. I'm quite easy learning.
...And, I'm working hard to improve my english. If something looks unclear, pls, any questions are welcome.

Thank you for reading!

Guys,

I can't believe that nobody has no such or similar experience.
Pls, give a clue, I don't need too much explanations.

There are two major questions for me:
1. How to make these End Points with public IPs accessible from I-net through the private address space?
- The first simple idea is to mantain a list of static routes at the router of Node1. But it's not flexible and will become nightmare with network growth.
- I guess there should be some kind of Route Discovering Protocol. What is the name of this protocol in MT OS?

2. Am i right about OSPF for the tasks described in the first message?

i would suggest ospf all over, one area should be enough.
then eoip to a central ac and pppoe to the clients. by that you can supply public ips, everything else means static routing as you mentioned or ospf at the clients (which is not really nice).
thats the standard-setup, proven to be very sexy to manage and repair, as it is pretty much self healing, especially in a situation like yours with many redundant paths. you should however take care of the path-costs, as you have different speeds on your links.

Thank you, thadem .

Good idea.

If I understood correctly, I need to configure EoIP tunnels between all the routers, so it will give me an extra address space (let's say for exapmle 192.168.1.0/24 ) where all the routers will be in the same subnetwork, so the public IPs of the end points will be transparently accessible too. It's correct?

not 100%

the eoip bridges the client-pppoe-traffic to your local ac.

with that your topology can change because of downtime, fire, whatever and the clients do not really have a service impact except a reconnect, as ospf takes care of the new route to your ac and the eoip-tunnel gets up after that again.

i do not know if that is exactly what you wanted, as i do not know with what your customers are connected (pppoe. static-routing, etc..). but it is a proven and stable design for an average wisp-network.

...Well, EoIP, and the whole your idea works for me!!
Thank you again, thadem.

2All:
New question:
it's appeared that my boss wants some nodes, for exapmle Node2 or/and Node4 (pls see the plan) could benefit the bandwith from both connections: 5Mbps and 50Mbps, so in total it should give to the client max 55Mbps. I constructed simple triangle in my lab, like in manual OSPF chapter, added cost=50 to one of legs. Now I traceroute and I see that OSPF creates routes bypassing all the time this expensive leg.
How to make it possible to use the bandwith of several legs in parallel, but in proportions to the cost of channels?
We need this because some of our end points placed in areas where it's difficult to provide good connection, so, for example, if such a Node has two connections, say 2 and 3 Mbps, then it would be nice to give it 5Mbps in total.
thank you.
