Multiple Interfaces with MANET

[platzhirsch]

Hi everyone,

I configured a network simulation with mobile clients using OLSR as
algorithm to build the routing table.

I connected my access points via ppp with a wired host. I configured
my simulation with **.interfaces = "prefix(wlan) prefix(ppp)" so the
OLSR hello packets are also ran on the wired host, works fine but for
one problem:

The routing table entry to the wired host is made on the interface
wlan and not ppp. As there is no wlan connection to the wired host an
assertion errors arises. Is it possible to fix this?

Seems OLSR adds only routing table entries on the wlan IF.

Best regards,
Konrad

I wrote a really really dirty pseudo-fix with activity, manually
chaning the value from wlan to ppp, however the AssertionError will
arise anyway, just some time later, because I use wait and there are
moments in the simulation when this fix blows up.

I really hope there is a configuration which has to be taken, because
this problem is the only one seperating me from finishing the
simulation :(

Best regards,
Konrad

If both interfaces have IP address the OLSR protocol should work.

different IP Addresses?

Furthermore the OLSR developer page says: Multiple Interfaces are not
implemented, so how could this work anyway?

Every interface must have a different IP address,  the OLSR indetify the output interface by the address if both interfaes have tha same address the protocol can't identify the interfaces

This is really valuable information, thanks for that.

Anyway, I am using now the NetworkConfigurator instead of
FlatNetworkConfigurator which assigns different IPs for each
interface.

Now, however, the ppp-IPAddress of my destination node is not
propagated to the wlan nodes which have no ppp interface.

I have 1 "internet" node with ppp Interface to 1 "access point" node
which also has a wlan Interface in order to connect to two "client"
nodes, which have only a wlan interface.



Best regards,
Konrad
