This shows how my nodes gets deleted:

1. I create a new Node


2. You see the node is there


3. Now I reboot the server
# reboot

4. For a short time the node is still there


5. But after about 1 minute the node disappeares


I attached the log of this test here.

I hope someone knows what the problem is.
Thanks in advance!

Hello

I have found the reason, but cannot manage it.
I have 2 identical Networks 192.168.11.0/24
Router 1 at Customer Voelk has on interface X1 192.168.11.1/24
Router 2 at Customer Koelbl has on interface X5192.168.11.1/24
Both have same Adress and I cannot change it.

2020.01.09 17:43:56.175 *D* [poll.conf          ] Primary IP address 192.168.11.1 of node Voelk SonicWALL TZ-500 [1268] found on interface X5 of node Koelbl Service SonicWALL NSA 2650 [80201]
2020.01.09 17:43:56.175 *D* [poll.conf          ] Node Voelk SonicWALL TZ-500 [1268] is a duplicate of node Koelbl Service SonicWALL NSA 2650 [80201]
2020.01.09 17:43:56.175 *D* [poll.conf          ] Removing node Koelbl Service SonicWALL NSA 2650 [80201] as duplicate


How can I resolve this Problem?

Thank you
Rainer

Hi,

one option is to use zones and put those routers into different zones. Another option is to mark internal interfaces as "exclude from topology". Second option is easier if you are not interested in anything behind those interfaces.

Best regards,
Victor

Hello Victor,

I have tried to "exclude from topolog" only 1 Router. But these did not work.
Then I built some zones. Now It seems to work pretty fine and no node will be deleted again.

Thank you very much
Rainer
