[Babel-users] How to setup Babel in a simple linear topology

[mason]

Hi,

I have a simple topology to configure a mesh network. Babel is running at
Node1-3 respectively.


                           10.10.1.121 (wifi)              10.10.1.122
(wifi)               10.10.1.123 (wifi)
PC1 ------------------- Node1 ----------------------------- Node2
--------------------------- Node3 -----------------PC2
172.16.1.20          172.16.1.121
172.16.1.122                     172.16.1.123          172.16.1.30

At PC1, it is possible to ping PC1 --> Node1, but it is not reachable to
Node2, Node3 and PC2.
At Node1, it can connect to PC1 and the rest of the Nodes.
On the other hand, at PC2, it is only reachable to Nodes3, not PC1, Node1
and Node2.

To freely connect among all of the PCs and Nodes, I think I may impose upon
on firewall at each interface of the device (PC or node).
Is there any way to solve this case?

In addition, at Node2, I can get the following routing table. Especially,
routing table flag of 172.16.1.123 or 1010.1.123 has to be U not UGH. Is it
something wrong?

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use

172.16.1.123     10.10.1.123      255.255.255.255 UGH    0      0       0

10.10.1.123       10.10.1.123      255.255.255.255 UGH    0      0       0

172.16.1.122     10.10.1.121      255.255.255.255 UGH    0      0       0
wlan0
10.10.1.122       10.10.1.121      255.255.255.255 UGH    0      0       0
wlan0
172.16.1.0         *                     255.255.255.0     U         0
0       0 eth0
10.10.0.0           *                     255.255.0.0        U
0      0       0 wlan0

Although I read some manuals about babeld, I have no idea what I have to do
next...
