1. Настройка Mikrotik:

1.1 Создание VLAN'ов на интерфейсе ether5

/interface vlan add interface=ether5 name="VLAN20" vlan-id=20
/interface vlan add interface=ether5 name="VLAN30" vlan-id=30
/interface vlan add interface=ether5 name="VLAN40" vlan-id=40

1.2 Задание ip адресов на VLAN'ы

/ip address add address=192.168.20.1/24 interface=VLAN20
/ip address add address=192.168.30.1/24 interface=VLAN30
/ip address add address=192.168.40.1/24 interface=VLAN40

1.3 Создание pool'ов для DHCP

/ip pool add name=dhcp20 ranges=192.168.20.2-192.168.20.254
/ip pool add name=dhcp30 ranges=192.168.30.2-192.168.30.254
/ip pool add name=dhcp40 ranges=192.168.40.2-192.168.40.254

1.4 Создание сетей для DHCP

/ip dhcp-server network add address=192.168.20.0/24 gateway=192.168.20.1
/ip dhcp-server network add address=192.168.30.0/24 gateway=192.168.30.1
/ip dhcp-server network add address=192.168.40.0/24 gateway=192.168.40.1

1.5 Привязка и создание DHCP серверов на VLAN'ах

/ip dhcp-server add address-pool=dhcp20 disabled=no interface=VLAN20 name=VLAN20dhcp
/ip dhcp-server add address-pool=dhcp30 disabled=no interface=VLAN30 name=VLAN30dhcp
/ip dhcp-server add address-pool=dhcp40 disabled=no interface=VLAN40 name=VLAN40dhcp

2. Настройка TP-LINK:

2.1 Создание VLAN'ов

vlan 20,30,40
vlan 20
  name "VLAN20"
vlan 30
  name "VLAN30"
vlan 40
  name "VLAN40"

2.2 Настройка интерфейсов

interface gigabitEthernet 1/0/2
  switchport access vlan 20
  
interface gigabitEthernet 1/0/3
  switchport access vlan 30
  
interface gigabitEthernet 1/0/4
  switchport access vlan 40
  
interface gigabitEthernet 1/0/10
  switchport mode trunk
  switchport trunk allowed vlan 20,30,40
  switchport pvid 20
