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 192.168.98.1/30 VLAN 98
second 192.168.99.1/30 VLAN 99

Is that correct ?
