Damian, thanks! That's actually roughly the range of losses we focused on; but it was based on my rough feeling for reasonable loss rates (as well as on experiments where we caused losses in emulated environments), and a reviewer - justifiably - asked if we can base our values on realistic

Re: Rogue objects in routing databases

Hi Florian, NANOG, While the symptom of (automatically) proxy registered route objects is problematic, perhaps we could also take this opportunity to discuss the underlying issue: we as an industry appear to place our trust in various IRR sources operated by entities that either can't or don't

Rogue objects in routing databases

It appears that there is currently an influx of rogue route objects created within the NTTCOM and RaDB IRR databases, in connection to Quadranet (AS8100) and China Mobile International (CMI). Examples of affected networks are: 193.30.32.0/23 45.129.92.0/23 45.129.94.0/24 Networks, which have

I suggest testing with a broad variety of values, as losses as low as 5% can be annoying, but losses at 50% or more are not uncommon. Damian On Fri, Jan 24, 2020 at 4:41 AM Amir Herzberg wrote: > Dear NANOG, > > One of my ongoing research works is about a transport protocol that > ensures

Don't forget to connect to peering exchanges and take their full routes too if you can.

Re: Dual Homed BGP

We have full tables from 2 ISPs at just one datacenter, and it is nice in the case of partial reachability issues—If one ISP loses access to routes to a destination but the other one doesn’t, for example. For us, the decision to do full tables was easy, as we are running 2 MX150s which can very

Re: Dual Homed BGP

Honestly, this. Your only real choice is what of 2 pipes to chuck it out of. Full tables vs partial and a default don’t make the process much more intelligent for 1 site dual homed, and as mentioned routing policy will have more influence. -Ben > On Jan 24, 2020, at 8:47 AM, Mel Beckman

Re: Dual Homed BGP

It’s pretty pointless for a small ISP to get full routes, because the BGP tables are so highly manipulated. It’s better to just get “company” routes for each upstream, and then use your own traffic engineering via prepending and static or policy routes to balance the outbound traffic the way
