[Babel-users] Babel Configuration Help

[Abraham Hart]

Hi,

I have 2 nodes on Openwrt Kamikazi 8.01.02. running babel 1.0.1, Node0 and
Node1

The nodes have 3 devices ath0 eth0 eth1.

Node 0
--------------
ath0 on node7 is statically configured as 10.0.0.1/24
eth0 on node7 is statically configured as 192.168.0.1/24
eth1 on node7 is statically configured as 192.168.127.1/24


babeld.config
----------------------------
interface ath0 hello-interval 1
redistribute ip 192.168.0.0/24
redistribute ip 192.168.127.0/24


Node 1
------------
ath0 on node5 is configured as 10.0.0.2/24
eth0 on node5 is configured as 192.168.254.1/24
eth1 on node5 is configured as 192.168.5.1/24

babeld.config
----------------------------
interface ath0 hello-interval 1
redistribute ip 192.168.254.0/24
redistribute ip 192.168.5.0/24

This causes babel to quit with an assert error from end_message in
messages.c
I've commented out the assert in the code and replaced it with an if
statement to alert me when it would normally have crashed.
edited end message
---------------------------
static void
end_message(struct network *net, int type, int bytes)
{
    //fprintf(stderr,"############ %i type, %i bytes %i sendbuf",type,bytes,
net->sendbuf[net->buffered-bytes-1]);
    assert(net->buffered >= bytes + 2);
    assert(net->sendbuf[net->buffered - bytes - 2] == type);
    if(net->sendbuf[net->buffered - bytes - 1] != bytes){
         fprintf(stderr,"####### crash, %i, %i, %i, %i", type, bytes,
net->sendbuf[net->buffered-bytes-1],net->buffered);
    }
    //assert(net->sendbuf[net->buffered - bytes - 1] == bytes);
    schedule_flush(net);
}

When edited like this it distributes the first route just fine but the
second route doesn't distribute
My added if statement also triggers quite a bit.

Here are the two "ip route show"

Am I misunderstanding what this does? What I am trying to do is something
like HNA's in OLSR, which work under the same network configuration. I need
nodes to be able to access all of the networks.
If so how could I get this working properly?

Attached is output of babeld with debug at 3

Thanks for the help,
Abe
