we would like to switch from EoIP to VPLS, but we encounter some serious problems with it.
If we try to establish a VPLS tunnel between 172.16.2.1 and 172.21.0.1 (or some other device in this area), the tunnel doesn't entry the running state.
Otherwise, a tunnel within an area works perfectly.
You can see a simplified network diagram in the attached image.
The problem seems to be at the border router (172.16.3.1 in this case).
Now let me describe our setup.
All our routers are running on 4.17.
As you can see, the OSPF is splitted in 4 different areas.
The backbone area is located in a house, all devices are connected with ethernet cables.
The connections between the border area routers and the individual areas are established with wireless.
Each area (17, 18 and 21) contains ~10-20 routerboards.
