[Olsr-dev] TC Redundancy and TC messages

Hi everyone,
I'm currently studying the OLSR code and I read about the bug in the
djikstra code so that the TC_REDUNDANCY is to be set to 2 (the code talks
about the 0.5.6 version, I'm currently using 0.6.1 but I assume the bug is
still there). I read here (http://www.olsr.org/docs/report_html/node53.html)
this sentence: "If all nodes in a MANET has TC_REDUNDANCY set to 2, then
all symmetric links in that network will be announced to all nodes. This
means that all nodes, not just the nodes selected as MPRs, will generate TC
messages". Those docs are really outdated, but if it's still like that, it
means that, as TC_REDUNDANCY values different from 2 are forbidden, all
nodes will always generate TC message?
Another doubt is about my test network configuration: I have an ethernet
test network. If I don't have any two hop neighbor, does the MPR
computation takes place only if I set the willingness to 7 (WILL_ALWAYS)?
It looks like that in the code, where if the 2-hop neighbor table is empty
then it will skip the computation.
Thank you very much for your help
