Hello all,
hopefully someone can help me to answer the newbie question:
Am i able to let OSPF decide which way to go, if around 10 mikrotiks (all in the same ip network) are spread at different locations, connected via powerline?
A quick introdution of what we want to do:
We have a powerline network with about 10 mikrotiks connected to them.
All mikrotiks have a powerline device connected to it.
They are wideley spread in a large building, where some powerline devices see each other and some not. Some have a greater signal strength and some loose the signal on some circumstances sometime. To get a most stable connectivity, we used to set up more powerline/mikrotik nodes for cross connectivity.
So we would like to have a system which freely decides, which way to do in order to get a stable connection, because if some nodes fail to work, the packet needs to go on other hops.
Example:
((MAIN_ROUTER <==lan==> MT-NODE-1 <==lan==> [PL])) ← - - -power- - - → (([PL] <==LAN==> MT-NODE-2)) ← - - -power- - - → (([PL] <==lan==> MT-NODE-3))
((+++++++++++<==lan==> MT-NODE-4 <==lan==> [PL])) ← - - -power- - - → (([PL] <==LAN==> MT-NODE-5)) ← - - -power- - - → (([PL] <==lan==> MT-NODE-6))
Description:
Everything between (( and )) are physically connected at one location.
MAIN_ROUTER is connected via LAN to MT-NODE-1 and MT-NODE-4;
MT-NODE-1 and -4 are connected via LAN to Powerline-Adapters;
Over the power network, they see MT-NODE-2 / MT-NODE-5;
… and so on…
MT-NODE-6 is able to see MT-NODE-3, but that link is not that good than MT-NODE-5 <=> MT-NODE-6, but in worst case, it can be used for a stable network.
As you see above, the mikrotik nodes are directly connected to the powerline devices. Its only one network interface for mostly all of them, except the ones directly connected to the main-router;
Right now it is done without ospf, just with a simple routing but if one node fails, the whole network fails because there is no failover.
A static failover will be hard to realize because some powerline-nodes see some other but not all see all others, so its hard to define a fix fail-over. However, if 2 or more nodes are missing (defective or something like that), even a simple failover setup will stop working.
Is this possible with a single area (eg. backbone) with a single ip-network (eg. 172.16.0.1/24, 172.16.0.2/24, 172.16.0.3/24, …) ?
The main router got the internet connection (default route).
Or isnt this possible that way, am i at the wrong path with ospf?
Any tipps on that?
Thanks and best regards,
Juergen
