Cisco Multi-Pod Configuration Error

AshSe
Level 4
Level 4

Hey experts, while configuring ACI, I am getting Value 4 collision error stating: "Encapsulation value 4 collides with INFRA". I understand that VLAN 4 is a default VLAN used by APICs and gets auto-configured in APIC and the same is used for inter (between Pods) and Intra (inside the same Pod) APIC communication. The same VLAN ID is used to configure "dot1q" encapsulation in IPN devices to ensure the communication (both Intra and Inter) in between APICs. Check the error below:

Please suggest the cause of this error and how to correct it.

Thanks
