Network Cutoff when pushing a Configuration Change to Logical Router

[AhmedBoujelben]

Hi Team,

We have faced a network Outage when pushing any Logical Router related configuration from Panorama to our managed firewalls. For example when associating new configured sub-interface to a logical-router and push the configuration to firewalls, there is a network outages for all existing production VLANs.

For example, When adding a new Sub-interface (ae1.901) which IP address is 172.20.201.1/29 to the Logical Router “LR_STAGING” and pushing the configuration from Panorama to Firewalls, all the already defined Production VLANs (ae1.200 and ae1.201) are impacted and we have noticed network cutoff of access to its servers (for example, Cutoff of access to server 172.20.200.9).

Panorama Version: 11.1.2-h3 PA-5410 Firewall Version: 11.1.2-h3

We need your support please.

Thanks, Ahmed
