Vertical Scalability of Route-Servers on very large IXP is a challenge!
We are talking about 400-2200 peers...

As already mentioned, Bird still does not deal very well with
multi-threading(even on version 2).
So, for that, thre
But you wrote that for scaling there are load balancers to balance
sessions among different bird instances. So VRRP + Load Balancer will
give you what you want. You can also try to bind several birds to a

And what about multiple peering sessions with multipath routing?

As I mentioned initially, my focus was on "large environments of IXPs".
Considering that, L3 anycast does not apply very well to that scenario.

the IXP.)
Using VRRP is an excellent method to provide fail-over on L2.

Hi,
You can use VRRP or alike protocol on L2 or dynamic routing with
anycast on L3 for reliability. I do not see what you want in Bird.
Could you explain more?

I was studying the concepts of multi-bird for large environments of IXPs.
And, beyond the extra complexity that it brings to the environment, one of
the weak points I saw was the fact that all the Bird instances are at the
same box(vm, container, etc...).
