Is it possible to extend the layer 2 network over the layer 3 network to the other site using Palo Alto
Basically I am trying to extend the VLAN to other site. Not sure if this can be achieved with Palo Alto. Any suggestion are welcome

just put the interfaces into layer2 mode and add them to a vlan (not a vlan interface, that's like a VRF)
add subinterfaces for each vlan tag you want to stretch if you're attaching trunk interfaces
below is a very basic example, in case you're not using trunk interfaces:
I have a small internet facing switch, and 2 internal switches. it's all a 'single vlan' so i'm not using tagged subinterfaces

Just because you can doesn't mean you should. Why do you want to extend L2 across sites?

Thank you for your response Reaper,
you are using the vlan on the same site but i want to extend this layer 2 vlan to the far end site using layer 3 network. Which seems to be difficult using Palo Alto

That is the exceptional requirement for the user, hence wanted to check if it is feasible on Palo Alto

ah you want to stretch L2 across sites over a VPN connection. This is not a function offered by Palo Alto (or any firewall AFAIK), this would be something that is handled by network equipment or a Telco/ISP/WAN operator
