Wireless Ethernet Bridge/Mesh encapsulation question

[jerry_ku]

how does Ethernet (Layer 2) data travel across a pair of FortiAPs setup in a Wireless Ethernet Bridge configuration?

For example, I have a Fortigate interface setup at 192.168.1.1/24. It's connected to an Ethernet mode FAP at 192.168.1.2. The FAP is on a switch alongside Server A at 10.1.10.6/24.

Another FAP is in Ethernet Bridge Mesh mode at 192.168.1.3 and is on a switch alongside PC A at 10.1.10.5. The mesh is connected.

If Server A has a DHCP server setup, when PC A does a DHCP REQUEST, does the Layer 2 aspect of DHCP get encapsulated BEHIND the IP address info of the FAPs in a packet? (ie: [Source IP 192.168.1.3] - [ Dest IP 192.168.1.2]  [payload of DHCP])? Or is all the DHCP stuff ignoring the 192.168.1.0/24 stuff of the FAPs entirely at this point?
