Hey guys, I just finished a new tutorial page on OSPF. I was going to make everything that is a “basic concept” part of the same tutorial, but as it started to get longer and longer, I thought it might be better to break it up into pieces. Anyway here is the first piece. I would love to hear your feed back on this.

From “Instances:”:
in a production environment, routers such as the RB1100, RB3011, and the CRS line would be better choices
CRS ?!! Or CCR? %)
Other question/note - often people creates loopbacks for OSPF router-ids. But it is Cisco implementation for automatic choosing of router-id (i.e. if no router-id is configured manually, the highest ip of the loopback interfaces is used. If no loopback interfaces then the highest ip of physical interfaces is used) and as I see in Mikrotik documentation - they don’t implement such method and router-id is just lowest active IP (or highest %)… i.e. in you case loopbacks will not be automatically chosen due to they are not lowest. Or I’m wrong? If yes - where?
I did mean the CCRs and I have changed that. Thank you for pointing that out. You’re right, MikroTik will not automatically select the Loopback IP address to be the Router-ID. It is best practice with MikroTik to create a Loopback and set the Router-ID manually.
Hi, do you try configure ospf over l2tp in ptp interface mode? Thera are some err on ccr 6.35. Incorrect routes are coming. Choose ptmp mode resolve this!
Have a good day!
