Full MikroTik MTCRE - OSPF (An Introduction to a GIANT of a protocol!)

Hello and welcome! In this video we will be looking at what OSPF is, how it works as well as how to configure this on a MikroTik device. You will learn about the backbone instance and area, how to change the Router ID. How to add interfaces to OSPF, how to add networks to OSPF and just a general feel for some of the quirks that comes with OSPF.

It is an amazing IGP that many Enterprise and ISP networks have been built on and I hope I can help you fall in love with OSPF as I have!

Thanks again for watching

Pinned comment with some details and ref material:

Correction at 29:08, this is a typo on my part and should have been 192.0.0.8/30. It still worked because this subnet is a part of the 192.0.0.0/8 supernet.

You are excellent as a teacher. Thank you for your dedication.

Thank you for all your help in understanding Mikrotik routing and configurations.

[mattxx]

great video series, was able to learn a lot from it and put it into practice.
Thanks a lot for this! 👍

1st comment my Master :) Shout out in your next vlog :)

[JesseArcher]

It would be great if you could update this OSPF video for RouterOS7

[m.l]

A good one, very useful - thanks! I'd love to see something like this about MPLS/VPLS too :) Or the new VXLAN is soo good that we could forget about VPLS?

Hello, Would you mind sharing the export from the EVE-NG?

[JasonJeschonek]

Hello and thank you for the great and easy to understand MikroTik videos, I have a question on the ospf area’s when do you have too many routers in any one area? Currently I have 20
routers in one area and I need to add 4 more, can I add them to my existing area 0 or would it be better to start to break them down? I also understand what you said about each one sending updates to each router and when you create different areas the abr sends the updates to the areas let me know thank you

The theory is sometimes boring, otherwise it is essential to understand what we are doing and why. So thank you, I love the theory 😉

Very very thanksful for your amazing and understandable video..!
But what program that you use to simulate this lab..?

[androidcomputers]

Air i have problem total 4 wan 3 wan on one side with loadbalancing and 4th as backup .error is when 3 wan internet is down 4th wan did not activate as 3 wan gateway is reachable . But if i disable interfaces of 3 wan than 4th wan activate .mean i have tried my best inrecursive routing and increased routing distance

[survivingnetworkingandit]

at 35:20 - we see the 192.0.0.8/30 route still showing on both gateways. Does that mean its using ECMP?

[gyorgykovacs]

Hi. I'm confused little bit. at 36:32 to reach 192.0.0.8/30 you changing the cost on R3 Ether1 and R2 Ether1. The failover link is on Ether5, it's not that what we have to change it? Because if i change Ether1 then in the routing table i get back again 2 gateways to 192.0.0.8/30 on R1. Thank You.

[rubigero]

hi can you create a core router connected to hotspot concentrator

[gyorgykovacs]

One more quiestion. The /30 (4 IP addresses) subnet mask for point ti point links have some advantages against /31 (2 IP addresses) subnets? Or that is just like a habit? Sorry for my silly questions. 😊 You are awesome teacher.

[nikolashuminosky]

in Mikrotik do we have manu to check LSU, LSR and LSACK, similar LSA?

[kresimirpecar]

One question for Dr.Network, is there any chance for MTCWE ? :)

[hit-]

Regarding RouterOS 7. According to MT, there is long-term release v7.1

[orangejvrski]

What simulation are you using in this presention. By the way. Its way too detailed.. thanks
