Virtual Interfaces and OSPF on a Mikrotik Router

Virtual Interfaces

To configure an virtual Interface you first have to set up a bridge and assign an IP Address to it.


You can use this interface like a normal physical interface.
 

OSPF

The Open Shortest Path First is a link-state routing protocoll.
You configure it under Routing-OSPF. As area backebone is used. Under networks the used networks are added.


Under interfaces you can now see the interfaces from the different networks. They can be configured as passive etc.

Configuring Mikrotik Router

There are serveral ways to configure a mikrotik router:

• CLI
• Webinterface
• Dude
• Winbox
• ...

We are going to use winbox. This is a tool from mikrotik. It works on Layer 2 and on Layer 3. This is very usefull, because you don't need a IP address to communicate. You can use packets to communicate instead.

Process:

• Start winbox
• Connect PC and Router with an ethernet cable (use last port)
• Connect via Ethernet (login is admin, without passwort)
• Reset Configuration (System - Reset Configuration - Select No Default Configuration)
• Get IP address via a DHCP Server (running on port that connects your router to the PC):
• Address List - add Address

• IP Pool - new IP Pool - set name  
• IP-DHCP Server

 

• Standardgateway, Subnetmask and DNS still need to be configured.

• Activate the Routing Internet Protokoll (RIP)
• Routing - RIP

 

• Add all networks, connected to you

•  Lookup all the routes

•  Test the connectivity with a ping: Tools-Ping
