[Olsr-users] Running Application with OLSR

[Brian K. Wong]

Hi, Markus,

 

Thank you for your reply. We have run tcpdump on  each node.
The result shows that OLSR traffic can pass and the routing
table is updated. Is it possible that this problem is caused
by VLAN? We are not sure about this.

can u first verify whether olsr traffic (broadcasts) can
pass your setup

 

a mean if u run tcpdump on each node, can u see incoming
olsr packets (port 698) on every node?

Hello, all,

 

We are running an application on top of OLSR. This simple
application involves one source node and one destination
node. The source node sends UDP traffic to the destination
node. 

 

This program works well when we run it on two physical
machines in the same wire LAN. However, when we run it on
two virtual nodes in the same virtual 

wireless LAN, the destination cannot receive any packets.
The virtual wireless LAN is described as follows:

 

The virtual LAN is implemented using tagged virtual LAN
(VLAN - IEEE 802.1Q) technology and network bridging. 

 

The VLANs are created using a Cisco Catalyst switch. For
virtual nodes on the same physical node, eth1 on the
physical node is connected to one port of the Catalyst
switch via a cat5 cable. Four VLANs - one for each TN - are
created on the switch port, with VLAN trunking enabled on
the switch port to allow data on all four VLANs to pass
through simultaneously. OLSR is running one this virtual LAN
for routing. 

 

Does anybody know the solution to this problem?

 

Thank you very much in advance.
