Connect two ovs bridges

Following the following steps to connect two ovs-bridges:

1. Create two devices using veth type:

     ip link add dev "int-to-prov" type veth peer name "prov-to-int"

2. Add int-to-prov port to br-int , set the type to be patch and peer altogether using the following
    two different methods:


     ovs-vsctl add-port br-int int-to-prov
     ovs-vsctl set interface int-to-prov type=patch
     ovs-vsctl set interface int-to-prov options:peer=prov-to-int

    or

    ovs-vsctl add-port br-int int-to-prov -- set interface int-to-prov type=patch options:peer=prov-to-int


3. Add the other port to the second bridge:

    ovs-vsctl add-port br-provider prov-to-int -- set interface prov-to-int type=patch options:peer=int-to-prov

4. Now bring both ports up:

    ip link set dev prov-to-int up
    ip link set dev int-to-prov up
