Hi All
I am trying to build a triangle topology as shown below but using in-band mode
In my attempts I only get this topology working when I enable STP
(spanning-tree) directly in openVswitch (ovs-vsctl set Bridge br1
stp_enable=true) or when I open the loop, to wait the controller communication
to be established and close the loop again.
Im using raspberry pi 3 as openvswitch with OVS 2.3.0.
When I try to use Ryu app as ofctl_rest.py, simple_switch.py ,
simple_switch_stp.py or rest_route.py running in-band mode without stp the
behavior of the switches is unpredictable. When I use theses same Ryu app
running a out-of-band mode the switches works normally.
I am setting inband networking communication with the command ip addr add
192.168.128.5/24 dev br1 (my controller stays in this same network), each
switch has three interfaces eth0, eth1 e eth2, about it, which one the switch
will be use to communicate when I set the ip directly in the bridge ?
Anyone knows if is possible to build a loop topology in in-band mode without
enable STP ?
Ryu Controller
