[Xorp-hackers] Error for XORP-OLSR when nodes are in different subnetwork

[Jiangxin Hu]

Recently I tested Xorp-OLSR for the scenario which nodes are belong to
different sub network. I got following errors in XORP log and routes are not
inserted into kernel table.
 
The scenario is very simple. There are two nodes, one address is 10.0.0.2/24
and another address is 10.0.2.3/24.

Is it a configuration error or it is a implementation limitation?
 
Thanks,
Jiang
