RE: BGP Traffic Engineering - Active\Passive

For the egress situation, you could also start looking at accepting full table from A and B, but apply a route-map to routes received from B to alter the local-pref based on the AS-PATH. > Is it possible to prepend to JUST one upstream ASN so normal traffic takes ISP A > back except 9999 traffic? to make: > > * ISP-A 1111 174 4444 > * ISP-B 1111 1111 1111 1111 1299 4444 > * ISP-A 1111 1111 1111 1111 1111 1111 174 9999 > * ISP-B 1111 1111 1111 1111 1299 9999 > > If I'm unable to do that will most provider prepend on your behalf so that ISP-A > would add the prepends for 9999 only? This is a conversation you need to have with A and B, or look at their transit documentation, where available. Several of them have communities you can tag your routes with to vary how it is announced, which may include announce/don't, prepend N times, set local-pref within their own network, and on a region / country / exchange / peer basis. If you really need this functionality, that may drive your choices for A and B. Obviously you'd again need route maps to apply to correct communities to your own routes only towards the correct transit provider. Take a look at, for example https://www.gin.ntt.net/support-center/policies-procedures/routing/ - no particular recommendation, just a well-documented example I have to hand. Cheers, Tim.

Comcast RPKI origin validation
by Tony Tauber 21 May '21

21 May '21

Last week we at Comcast reached some substantial milestones in our RPKI rollout (validation on inter-provider sessions, ROAs for our address-space). Jason Livingood and I collaborated on a blog post, FWIW. https://corporate.comcast.com/stories/improved-bgp-routing-security-adds-an… Please forgive the somewhat less-technical public-facing verbiage. Thanks for all the support of people inside Comcast, particularly Courtney Smith, and also folks in the community on this long journey. (We have lots of address space spread over more than 20 regional networks as well as our Backbone network which made the ROA part a bit complicated. I issued over 9k ROAs or about a quarter of ARINs total.) Cheers, Tony https://rpki.cloudflare.com/?ohlcTa=ARIN&ohlcDate=18723&view=statistics&pre… [image: image.png]

FCC accelerates STIR/SHAKEN deadlines
by Sean Donelan 20 May '21

20 May '21

The Federal Communications Commission voted today to accelerate the STIR/SHAKEN deadlines for certain small IP voice service provider networks to no later than June 30, 2022. Large IP VSP networks had a deadline of June 30, 2021. Shockingly (I'm shocked, shocked to find that gambling is going on in here) the commission found a subset of small voice service providers appear to be originating a large and increasing quantity of illegal robocalls. According to the FCC NPRM, a March 2021 report released by Transaction Network Services, a provider of call analytics, found that the problem of robocalls originated by certain smaller voice service providers has gotten worse: by the end of 2020, "[a]lmost 95% of high risk calls originate from non-Tier-1 telephone resources, up 3% from last year."

Buying IPs with poor reputation
by Ross Tajvar 19 May '21

19 May '21

I'm curious if anyone has experience deliberately buying blacklisted blocks, or blocks that otherwise have poor reputation. Is there a significant price difference? How do you seek them out? Most of the sellers I've found seem to focus on blocks with good reputation, or on improving the reputation of a bad block. But I am interested in purchasing some IPs for internal services where reputation doesn't really matter. Thanks, Ross

NAT/CGNAT IP address/users ratios
by Scott, Thomas 18 May '21

18 May '21

Hello NANOG (and friends), Asking if anyone would care to share their CGNAT and NAT ratios. We're looking at some best practices and I wanted to see what the community at large has seen working, and not working. I am by no means a NAT expert, and usually I see the other end where it's clearly *not* working. Does anyone have estimating formulas for devices/users to internal blocks to public IPs?

Georgia DOL Contact

Is anyone on the list with Georgia Department of Labor? I've got customers having problems logging into their website and need a good contact there to troubleshoot. Routing appears ok as we can get to hosts on that subnet, so I suspect the issue is above layer 3. Thanks- Joe
