Create links between mininet switches emulated on different machines

I need to break the network into parts and emulate each part on my Linux machine. For example, on machine No. 1 the following topology is launched:

    class MyTopology(Topo):        def __init__(self):            super().__init__()            s1 = self.addSwitch(name='s1', protocols='OpenFlow13', dpid='0000000000000001')            h1 = self.addHost(name='h1', ip='1.2.3.1/24')            s2 = self.addSwitch(name='s2', protocols='OpenFlow13', dpid='0000000000000002')            self.addLink(s1, h1, delay='5ms')            self.addLink(s1, s2, delay='5ms')

On machine No. 2 the following topology is launched:

    class MyTopology(Topo):        def __init__(self):            super().__init__()            s3 = self.addSwitch(name='s3', protocols='OpenFlow13', dpid='0000000000000003')            s4 = self.addSwitch(name='s4', protocols='OpenFlow13', dpid='0000000000000004')            self.addLink(s3, s4, delay='5ms')

I want to link the switches s1, s3 and s2, s3. To get the topology:

+-----+               |  h1 |+-----+                 |                 |                 |+----+-----+            |    s1    |+-----------+           /             \          /               \+----+----++----+----+     |    s2   |----------|    s3   |+----+----++----+----+                          /                         /+-----------+            |    s4    |+----+------+

I tried to do

    Intf('enp0s9', node=s1)    Intf('enp0s9', node=s2)

by car No. 1.

    Intf('enp0s9', node=s3)

by car No. 2machines are connected to a local network by the "enp0s9" interface, but when you try to attach one interface to two switches, they stop connecting to the controller.
