1. Comment Interface
/interface ethernet
set [ find default-name=ether1 ] name=ether1-WAN1
set [ find default-name=ether2 ] name=ether2-WAN2
set [ find default-name=ether3 ] comment="# LAN"

2. Create Bridge-Vlan
/interface bridge
add fast-forward=no name=bridge-VLAN

3. Create Vlan
/interface vlan

add interface=bridge-VLAN name=vlan20 vlan-id=20
add interface=bridge-VLAN name=vlan21 vlan-id=21
add interface=bridge-VLAN name=vlan22 vlan-id=22

4. Configure IP Address for WAN
/ip address
add address=96.9.74.110/24 interface=ether1-WAN1 network=96.9.74.0
add address=203.217.170.111/24 interface=ether2-WAN2 network=203.217.170.0

5. Configure IP Address for LAN
/ip address
add address=10.10.10.1/24 interface=vlan10 network=10.10.10.0
