Open vSwitch is looped

Good morning,

I try to set up a connection between OpenDayLight controller and a router with an Open vSwitch switch between them. The switch connects successfully to the ODL, but the problem is that the two interfaces of the switch are looped, so I can't ping the switch with my router.

I seemed to find a solution for this here: http://docs.openvswitch.org/en/latest/faq/issues/ , but I wasn't able to solve the problem.

Any kind of help is well appreciated.

Thank you in advance,

Davide
