Hey guys, what are your real-world results on how many routes / peers a CCR2216 can handle? I know there are some BGP bugs between 7.16-7.18, which hopefully are fixed now.

4 full tables shouldn’t be an issue with 16 GB RAM. Just curious, though: why do you need 4 full BGP tables? Are you running a big exchange or acting as a transit network?

4 full tables shouldn’t be an issue with 16 GB RAM. Just curious, though: why do you need 4 full BGP tables? Are you running a big exchange or acting as a transit network? We’re just a WISP up in North-Central Idaho. The idea is to have redundancy, and as much connectivity as I can. I want to …

Got it, redundancy makes sense. And yep, each BGP session with Cogent and HE at each location will give you a full table if you request it.

I strongly advise against using v7.19.1 in production since it’s just been released. We’re sticking with v7.15.3 until the 19.x branch proves stable enough for production use.

We have been running the CCR2116s with about 2 full tables not facing any issues so far on 7.15.x. I have to check on the L3HW offloading on some routes though. The routers did handle around 10 Gbit/s of traffic at peak without any issues / high cpu as well. We will connect one of them to a large Eu…

Well, there are a bunch of other ways to hardware offload, but as long as you don’t throttle the CPU at 100%, there’s no need to worry about it. But if you do find yourself hitting 100% all the time, it might be worth looking into route selection for hardware offload. There’s a thread about this fr…
