Hello 

Is olsr not a multi path routing protocol, please correct if I'm wrong.
 
I made a setup of four nodes in a ring topology

  -A-B-C-D-
 |         |
  --------- 

Node A has 

wlan0wds0 inet addr:20.1.1.1  Bcast:20.1.1.255  Mask:255.255.255.0
           
wlan0wds1 inet addr:30.1.1.1  Bcast:30.1.1.255  Mask:255.255.255.0

          
Node B has 

wlan0wds0 inet addr:20.1.1.2  Bcast:20.1.1.255  Mask:255.255.255.0
           
wlan0wds1 inet addr:40.1.1.2  Bcast:30.1.1.255  Mask:255.255.255.0

Node C has 

wlan0wds0 inet addr:40.1.1.1  Bcast:20.1.1.255  Mask:255.255.255.0
           
wlan0wds1 inet addr:50.1.1.1  Bcast:30.1.1.255  Mask:255.255.255.0

Node D has 

wlan0wds0 inet addr:50.1.1.2  Bcast:20.1.1.255  Mask:255.255.255.0
           
wlan0wds1 inet addr:30.1.1.2  Bcast:30.1.1.255  Mask:255.255.255.0

A multipath protocol should have shown two paths to node C i.e. through
node B and node D but this shows only one route.

please explain this.

Thank You
