Fortilink 3rd Party Switch L2

[Gumo]

I want to configure FortiLink over a point-to-point layer-2 network for connection to FortiGate Firewall and Cisco BB (Backbone). I need to connect FortiSwitch via Cisco BB. I'request support on how I can perform this configuration.

The environment have: Fortigate > Cisco BB > FortiSwitch

Been labing several topologies this weekend and finally got the L3 working.  Turned out my old 3550 Cisco  switch could not handle VLANs above 1K do had to change the default Fortilink management vlan.

Thats correct, p2p is not possible in this design. p2p means FGT-FSW-cisco-FSW.

Fortilink over layer3 is the correct approach.
