inter-vlan routing

2022-08-10 13:28:23

Tags: #VLAN & Multi-Networks

Model: TL-SG3428

Hardware Version: V2

Firmware Version: 2.07

Could anyone help to explain how to configure based on TP-Link devices? I have couple times that but I have no way to communicate between inter-vlan.

My goal is each VLAN should be able to communicate with each others and able to out to ISP. Do I have right devices (VPN router and layer 2+ switch) for this inter-vlan routing?

@GaryPang

You may misunderstand VLAN and VLAN Interface, depending on your needs, it seems more appropriate to set up different VLAN interface.
It is easy to implement because you have ER605, check this:

How to create multi networks and manage network behavior with ACL

If you set up VLANs, under normal circumstances, different VLANs will not be able to communicate with each other and will be separated.

However, if you set up VLAN Interface, you can have multiple network segments and different VLAN Interfaces can communicate with each other.

Just striving to develop myself while helping others.

L2+ switch configuration: Each VLAN will need an interface configured and enabled, e.g. 192.168.1.1 on VLAN 1, 192.168.66.1 on VLAN 66.

Hosts: Set up a PC on VLAN 1 with IP address 192.168.1.2, netmask 255.255.255.0, and gateway 192.168.1.1. Set up a laptop on VLAN 66 with IP address 192.168.66.2, netmask 255.255.255.0, and gateway 192.168.66.1. Verify that the PC can ping the switch and the laptop.

Routing: Choose an unused network, e.g. 172.31.255.0/30. Configure port Fa1/0/24 on the switch as a routed port with address 172.31.255.2 and netmask 255.255.255.252. Configure a port on the router with address 172.31.255.1 and netmask 255.255.255.252. Verify that the router can ping 172.31.255.2 on the switch. On the router, add route 192.168.0.0/16, with next hop 172.31.255.2. Go back to the switch and add route 0.0.0.0/0, next hop 172.31.255.1. The PC and the laptop should now be able to ping 172.31.255.1 or anything reachable from the router. Assuming the router has a public address on its WAN interface, the internet should now be reachable from networks 192.168.1.0/24 and 192.168.66.0/24.
