Yes it should change the metric for this route. But it does not.
Here is a example how the routing looks like from txt_info-Plugin:
VIEW IS FROM INTERNET-ROUTER as specified in my last mail in section
Network-Design / Schema...
The focus is on 172.16.12.160/27 it should be routed via "bond0"
> ROUTE HOST Metric Interface
> 172.16.12.32/27 172.16.12.4 1 1.000 bond5 # ROUTER B.1
> 172.16.12.96/28 172.16.12.4 2 2.000 bond5 # ROUTER B.2
> hidden node on metric 3
> 172.16.12.128/27 172.16.12.4 4 4.000 bond5 # ROUTER C
> 172.16.12.160/27 172.16.12.4 5 5.128 bond5 # ROUTER D
>
> 172.16.13.160/27 172.16.12.5 1 1.000 bond0 # ROUTER A.1
> 172.16.14.32/27 172.16.12.5 2 2.000 bond0 # ROUTER A.2
> 172.16.13.32/27 172.16.12.5 3 3.000 bond0 # ROUTER A.3
This route should only been selected if "bond0" failed.
This is the route as it should be:
> ROUTE HOST Metric Interface
> 172.16.12.32/27 172.16.12.4 1 1.000 bond5 # ROUTER B.1
> 172.16.12.96/28 172.16.12.4 2 2.000 bond5 # ROUTER B.2
>
> 172.16.13.160/27 172.16.12.5 1 1.000 bond0 # ROUTER A.1
> 172.16.14.32/27 172.16.12.5 2 2.000 bond0 # ROUTER A.2
> 172.16.13.32/27 172.16.12.5 3 3.000 bond0 # ROUTER A.3
> 172.16.12.128/27 172.16.12.5 4 4.000 bond0 # ROUTER C
> 172.16.12.160/27 172.16.12.5 5 5.000 bond0 # ROUTER D
So the weight parameter does not apply. Is this a bug in OLSR?
The weight parameter is activated on ROUTER C.
ROUTER C sees ROUTER A.3 and ROUTER B.2.
ROUTER C gives ROUTER A.3 a weight of 5 and ROUTER C weight of 10. So
ROUTER A.3 should be selected.
