Hi all,

I try to interconnect 3 pve nodes for testing ceph using an ovs bridge like described in example 4.
The packages ifupdown2 and openvswitch-switch are installed on every node.

Now I'am a bit lost to ping between all 3 nodes. Maybe it's blocked by faulty rtsp configuration?
The stupid case, it works until a reboot of PM1 and PM3.
The PVE-Firewall is not in use on all 3 nodes.
All nodes are running 7.1-9.

IP Subnet 10.55.55.0/24
VLAN 55
Code: 
|-------|               |-------|
| G G X-------------------X G G |
|     X |               | X     |
|------\|               |/------|
   PM1  \               /  PM3
 .55.60  \             B .55.62
          \           /
           \|---  --|/
            \  G G  /
            |X     X|
            |-------|
               PM5
             .55.64

Ping PM1 -> PM3 not possible
Ping PM1 -> PM5 ok
Ping PM3 -> PM1 not possible
Ping PM3 -> PM5 ok
Ping PM5-> PM1 ok
Ping PM5 -> PM3 ok

In case I remove the interconnection cable between PM1<->PM5 I am still able to ping from PM1 to PM5 (over PM3).
