routing table unmodified

Is there a config option that tells olsrd not to update the routing table?
Olsrd should do all it normally does, except to update the routing table.
Thanks.

No. But if you are on Linux, you tell olsrd to update some other
routingtable than the default one and let the kernel ignore it
completely - which should have the same effect with the only difference
that you can actually see what's the current status is.

I understood what you said... it is even better to do in the way you suggest.
Can you tell me what's the option which tells olsr to do that?
Thanks.

The above is more an unintended fallout of that feature.

You need a pretty recent release and the option is "RoutingTable" IIRC
and takes an integer as parameter.

Re: routing table unmodified

Hi,

write plugin. Something like:

#include process_routes.h
init() {olsr_addroute_function=0;}

OLSRv5.5 questions

Hi,

I just have a few questions about the configuration options in olsrd 5.5.

1. What is the FIBMetric? Is FIB an acronym for (Forwarding Informatoin 
Base)? What is the difference between flat, correct and approx.

2. The LinkQualityWinSize. Is this the number of LQ packets over which 
the link quality is averaged? Also the PollRate, is this the frequency 
that the LQ is checked by the routing protocol?

3.Under the Interfaces section of the configuration file there is a 
HelloInterval and a HelloValidityTime. The hello interval how many 
times a second hellos are sent out and the validity time is the number 
of seconds that they are averaged over? This leaves me a little 
confused as to the difference between the LinkQualityWinSize and the 
HelloValidityTime. From my understanding they are both the number of 
hello messages over which olsr is averaged.

Thanks for your time

Dave

Yes.
flat: every route gets "2" if the route is send to the kernel. This
avoids route changes just because the metric of a route changed and it
isn't necessary anyway.

correct: The metric on "ip route" is always the correct one.

approx: olsrd sets the correct metric but doesn't update because because
of route changes. So the metric value "ip route" is not necessarily
correct.

Re: routing table unmodified


Giovanni,

I have an experimental olsr_filter plugin that does what you want  
( if I understood you correctly).
The original source was by wolfgang nagele, heavily modified now and  
still not 100% ok.
But if you want to hack on it, I can send it to you.

a.
