After R82 Multi Domain Management Upgrade: VALIDATION Error on SMB interfaces without ip address

[Ilovecheckpoint]

Hello,

We have just upgraded a Multi domain from R81.10  Jumbo Take 177 to R82 Jumbo Take 44.

On one domain, it shows validation errors all retated to 3 SMB with no ip addresses on topology interfaces:

"All network interfaces must define IP addresses" and it show which is the interface.

I do not need to have these interfaces, so I deleted them, exited and reentered on the dashboard, and now the same validation error, shows instead of the interface name, "unknown".

I discarded and tried differently, I deleted one of these gateways on validation error, which is no more on production, then published. Closed and reopened the dashboard and the problem is exactly the same as when I deleted the interfaces who were without the ip from topology.

My only option now is to revert, but I have modified the default implied rules after the upgrade, and deleted this gateway, so I prefer not doing it.

What next ?

@Ilovecheckpoint  Last week I catched the same with 50 SMB devices (15xx). The topology definition of the gateways objects in R81.10 was at default. No IP addresses defined and only default objects like WAN DMZ LAN_Switch etc. And topology followed routing.

We configured the topology correctly. Removed all interfaces from the topology tab added WAN with dynamic IP and LAN with the correct IP configuration. For most of the objects we got the configuration via the „get topology with networks“ but some were a manual process. After that all validation errors are gone. 

If you have three SMB devices I believe you have the same validation errors for all devices. If you click the mentioned interface from the validation errors you end up in the correct SMB gateways topology configuration.

I read what @Wolfgang provided and it seems totally valid. In case it does not fix your issue, definitely open TAC case.
