if you are connecting back to back with router and configure router side as trunk, you need to provide sample config and what is the issue you having to recommend best.

Hi Bandi,

Thank you very much for your help!

My problem is:

I am trying to connect directly ASA5506X (subinterface (vlan314) - OUTSIDE interface) with Cisco C881 (Fa0- access to vlan314), but they couldn't communicate with each other. In case of scenario 2 as the attached picture in previous post, they could. In fact, I must implement the system following scenario 1. I don't know why they couldn't communicate. What should I do to follow scenario 1?

I attached the configuration for the reference. I highly appreciate any suggestion!

Thank you so much!

BRs,
