Not a good way you will probably break stuff if you do it this way… Unkown, Mikrotik’s documentation says they support confederation in v7 Moved to AS, you place the confederation AS then a “/” then your router’s AS V7 command “routing/bgp/connection/set default” v6 command “/routing bgp instance set default” While you no longer “need” the instance menu Templates is pretty useful for replicating the features it gave us.
While it was tempting, it frequently caused beginners to create headaches for themselves that were not simple to diagnose or understand the issues. Technically Instance is entirely gone, you no longer need to create separate instances of BGP (nor did you really ever need to). Template is more accurately described by it’s name, think of it as a reusable group of settings that you can apply to different BGP connections. If you need to separate out your routes, send them to a unique VRF. Practically, this doesn’t mean all that much to the simple user, or even an advanced user. Unlike in v6 there are no longer different BGP instances, just different VRFs. You can think of Instance being moved completely over to Template, but you would have the wrong idea and get yourself into trouble if you do. Which used to be all you needed to get your router talking BGP to an upstream provider or internally in your network. I am just going to give a broad overview of how v7 replaces, or doesn’t, Instance, Networks, Aggregates and Advertisements menus. Mikrotik has removed all of the old menus. This means that an export backup from v6 will not work be importable in v7 if you are running BGP, I believe this issue effects OSPF and a few different menus. You might also catch some holdover issues with your configuration. Mikrotik has done a ton of work to make a direct conversion work (in both directions, you can downgrade your router and get your old configuration back, though Mikrotik does not promise this so don’t bet money on it…). With the most significant issues being in filters. I would highly recommend duplicating your config on to another router running v6 and doing a straight upgrade to RouterOS v7.1, I have done it multiple times and it works pretty well.
Note, all of my examples of RouterOS will be from 6.48.1(v6) and 7.1(v7) since that’s what I am running on my home router. If people want to help me out with some of the missing information I would be more then grateful. I just am wanting to aggregate some info so I can direct people to it. This is not supposed to be exhaustive, my knowledge isn’t.
I will give a bit of a summary of the differences between Mikrotik’s RouterOS v6 and v7 BGP setup and configuration.
