Re: ROS 7.1 BGP max-prefix-limit missing

Let's use Microsoft AS8075 as an example. On their PeeringDB entry (https://www.peeringdb.com/net/694) they specify that peers should see no greater than 2000 v4 and 500 v6 routes and to assume there is an issue if a peer receives anything greater than this. If a peer hits a limit it should do an a...

Re: Feature Request : IPv6 Fasttrack

Has Mikrotik ever provided an answer to this request?
Is it even feasible on the hardware side of things?

Re: ROS 7.1 BGP max-prefix-limit missing

Small update. We are working on this feature. Currently there will be two options: * do not break session but throw the warning that limit was reached; * break the session on the limit, reconnect will require the administrator actions, otherwise the session will stay down indefinitely. Also by not ...

Re: ROS 7.1 BGP max-prefix-limit missing

Considering how many people intervened and explained why having a max-prefix-limit is important, is there an official decision on Mikrotik's side? I honestly don't understand the resistance on implementing such a simple function that was already present in ROS 6 and that every competing product alre...

Re: ROS 7.1.2 BGP Ignoring local-pref and bgp-weight

Set to use the same template and the same router-id for both connections.
You are right, it was the router-id.
Thanks for the help.

Re: ROS 7.1.2 BGP Ignoring local-pref and bgp-weight

BGP from one instance can install only one best route. From your route output it appears that each route is received from its own BGP instance. In this case of course bgp best path selection is not applied. Yes the two routes are received from two different sessions but I really don't understand wh...

ROS 7.1.2 BGP Ignoring local-pref and bgp-weight

Hello, I have a CCR1036 that receives a FIRT from my transit and I also have a peering session in an IXP. I have filters that set the local-pref of all the routes that I receive from the IXP's Route Server at 150. Google announces its networks on my IXP and testing I noticed that I was being routed ...

Re: ROS 7.1 BGP max-prefix-limit missing

There is as safety pin mostly for IX. You know that IX has 100-2500 routes. If this goes over 5000 something is wrong and its better ti drop. That and not only for IXs. Think about what happened yesterday with Cloudflare leaking all Akamais routes, in this case you would have simply shut down the s...

Re: ROS 7.1 BGP max-prefix-limit missing

currently session does not show prefix count, but you can get route count either by printing routes from the routing table with print count-only or use /routing/stats/origin which shows total route count for each process So there's no way to limit the number of prefixes pushed by the other peer in ...

ROS 7.1 BGP max-prefix-limit missing

Hello to everyone, I'm new to routing and Mikrotik and I've decided to pull the trigger and start my journey with ROS 7. I didn't have any particular issue with setting everything up apart from the max-prefix-limit which seems to be missing. I've tried searching in Mikrotik's documentation for ROS 7...
