[OLSR-users] Anyone tried two nodes with internet connection?

[Rajesh Narayanan]

Hi,


                             *  *                         *  *
                             |  |                          |  |
InternetA--------->Node1 <-(OLSR)->  Node2---------->InternetB
                             ^                              ^
                             |                               |
                             |                               |
               Wired link laptop A        Wired link laptop B
                  (HNA4)                        (HNA4)


I got the dyn gw plugin up and running and configured as suggested. Well the
problem is that :
* Assume I remove the link the InternetA (cable disconnect to simulate link
failure)
* Node 2 gets notified that a route does not exist to the internet anymore
* But the Route to internetA still remains in Node 1!!!
* Node1 tries to route the pings (to google.com) via this interface since
its the default route
* As the default route does not get removed (due to link failure) the OLSR
link is not chosen.
* If I manually remove the default route, only then the Node1 forwards the
pings via Node2 and out.

What am I doing wrong? Any other config issues I need to look at??

Thanks,
Rajesh
