Re: [B.A.T.M.A.N.] batman routing clarification

Hi -

which version of batman are you using? And you should provide us with more 
details. Just saying Link is 'poor' or 'good' is very unprecise. Remember: A 
direct route with 6 Megabit performs similar to a two-hop link with 12 
Megabits on each link, since no retransmissions have to be made.

If you set the routes manually, it would be interesting to know the transfer 
performance of the following: 

A->C
A->B
A->B->C
C->A
C->B
C->B->A
 

How many OGMs does A count directly from C and via B? (And vice versa)
By the way: -o 3000 is quite slow for sending Originator messages if you have 
20 nodes only. The default should be fine.
