2 Peplink one lan to other wan port

I have 2 Peplink 380.

Both Peplink have 2 Wan

I have both peplink in same fiber ring with same (different) VLAN routed.

I created a VLAN (not routed ) in first Peplink and put it in Free wlan of second Peplink

Same in other peplink.

first VLAN 98
second VLAN 99

Is that correct ?
