Missing IRINN route objects & outage!

A friend of mine buzzed me yesterday about his missing route objects. Later multiple other ISPs told the same story which triggered me to put this as a question on INNOG Mailing list. Many folks replied of missing route objects there and it seems to be limited to IRINN members only. I also asked the same question on APNIC mailing list and it was again confirmed about the issue.
Before I proceed further, here’s what it is all about.

What are route objects?

Route objects are basically entries created at an Internet Routing Registry (IRR). The key idea here is that an ISPs writes in a public register on what they want to do before they actually do. This gives a way for ISPs to transparently share their intentions in the global routing.

Example of a route object

anurag@devops01 ~> whois -h whois.radb.net 2402:b580::/32
route6:     2402:b580::/32
descr:      Anurag Bhatia R&D Pool
origin:     AS58901
mnt-by:     MAINT-AS58901
changed:    me@anuragbhatia.com 20200205
source:     ALTDB
anurag@devops01 ~>

E.g here I want to originate 2402:b580::/32 with my origin ASN 58901 and IRR which is giving this data is ALTDB. One can read more about route objects in my talk given at INNOG last year here. Another good detailed reading can be seen on FCIX here. Various operators build automated BGP routing filters based on the IRR data. So e.g anyone who is peering with me @ AS5891 can do:

anurag@devops01 ~> whois -h whois.radb.net !6as58901
A83
2402:b580:1::/48 2402:b580:3::/48 2402:b580:2::/48 2402:b580:4::/48 2402:b580::/32
C
anurag@devops01 ~>

This gives currently registered route objects and hence can be allowed on BGP filter.

What is IRINN?

IRINN or Indian Registry for Indian Names and Numbers is National Internet Registry (NIR) which functions closely with Regional Internet Registry (RIR) – APNIC in this region. While RIR is responsible for allocating IP addresses and AS numbers in the region, NIR is responsible for doing that within given National area. Broadly NIRs exists to facilitate and make it easy for local operators to interact directly with a local organisation in the local language, currency, timezone etc. Some other countries which have NIRs include China (CNNIC), Japan (JPNIC), Taiwan (TWNIC) etc. Indian NIR i.e IRINN is operated by NIXI (National Internet Exchange of India) and works closely with Ministry of Electronics & IT, Govt. of India. Indian ISPs, datacentres, web hosting companies, universities, banks and just anyone who needs IP address or ASN can get that from IRINN or APNIC.

Route object management at IRINN

For IRINN members, unfortunately, there’s no local IRR and basically all IRR entries go to the RIR (APNIC) run IRR. So instead of IRINN members managing those route objects directly with APNIC, they request those changes with IRINN and IRINN team does that manually in APNIC’s database. I covered this in detail in a previous blog post here.

Mass outage on 3rd and 4th July 2020

On 3rd July 2020 suddenly a large number of registered IRR route objects went missing from APNIC’s database where the maintainer was IRINN. There are no reported cases of any non-IRINN members with this issue. As far as I personally know – Tata Communications AS4755 is known to be filtering their Indian customers based on IRR data and regenerate filters every 6 hours. In the case of Airtel AS9498, I don’t think they automatically generate filters. Let’s see what was visible in the routing table.

A starting point can be RIPE RIS RRC03 because that is directly fed with full routing table from Tata Communications AS6453 which is technically direct upstream of Tata Communications AS4755 in India. Raw MRT dumps for RRC03 are here. It has around 12 routing table dumps (at time of me writing this blog post) for July 2020. Extracting only AS6453 data from it, that gives following total route announcements of AS6453.

An AS_PATH filter of ^6453 4755_ and counting total routes across 12 dumps in July gives me this.

Dump at 20200703.0800 has 17683 while dump after 8hrs of that at 20200703.1600 shows 17194. That’s a drop of 489 prefixes. That is likely not giving a complete picture since it’s 8hrs of time. Though Airtel, Tata or Jio do not feed Oregon route views collector. I am still curious about looking at Oregon Route-views dumps for _6453 4755_ as well as _9498_ and _9583_ dumps to check for any noticeable drop in the routes in the table. There are 34 visible dumps for July there (at a gap of 2hrs) between 2nd July – 4th July and that can give a more refined picture. Assuming if Tata Communications actually pulled off routes, those would be visible via various other networks who dump full table at Oregon route views.

Also, there is data available for withdrawal and announcements at every 15mins via Oregon route views. So I put code to read 300+ dumps for announcement and withdrawal data and plotted that.

So in the following graph, we find a drop of 600+ prefixes between 12:00 and 14:00 UTC on 3rd July 2020.

7/3/2020 18:0017451
7/3/2020 20:0017448

Looking at the diff of dump between 7/3/2020 12:00 and 7/3/2020 14:00 we can see 669 prefixes belonging to different ASNs which went offline and were not visible behind Tata Communications AS4755 at least for 4 hours.

Out of these 669 prefixes, I see 566 belong to MAINT-IN-IRINN maintainer and spread across 161 unique network ASNs. I have posted a list of prefixes, AS number and AS names below.

The issue in total took a much longer time as APNIC/IRINN restored the route object database and ISPs across the world re-generated their filters. Likely it took Tata Communications time between 14:00 to 18:00 UTC / 7:30 pm to 11:30 pm IST on 3rd July 2020 to disable IRR based filters.

Besides many ISPs it also impacted a few banks:
AS136252 – BANK OF BARODA
AS137108 – Bank Of India
AS59197 – Bharatiya Reserve Bank Note Mudran Pvt. Ltd
AS132994 – DENA BANK

Indian IPv6 deployment

I had calls with a couple of friends over this week and somehow discussion IPv6 deployment came up. “How much has been IPv6 deployment in India now in 2020” is a very interesting question. It’s often added with – “how much of my traffic will flow over IPv6 once it is enabled“?

Game of numbers

There is a drastic difference in IPv6 deployment depending on which statistic we are looking at here in India. There can be a bunch of factors based on which we can try to judge IPv6 deployment:

  1. How many operators are offering IPv6 to end users?
  2. How many end-users are on IPv6?
  3. How’s the content available on IPv6 in terms of a number of IPv6 enabled websites?
  4. How’s the content available on IPv6 in terms of traffic volume over IPv6?

First two and last two points are related and point towards from vertically opposite ends. (Call it good or bad) the fact of high centralisation. There has been an ongoing centralisation of mobile operators and in-country like ours they connect a very large number of end-users. The number of fixed-line networks has increased considerably but at the same time in proportion to a number of mobile users they user base growth has been much lower.

On the content side like everywhere else in the world, there’s a lot more centralisation of content. Many of my Indian ISP friends tell me that Google + Akamai + Microsoft + Netflix + Facebook + Cloudflare is way over 75% of their traffic. Think about it, that’s just 6 AS number out of 68000+ odd networks in the world as per BGP routing table. Thus by traffic profile, we are looking at 0.0014% networks serving 75% of content traffic. The reason for such centralisation is actually beyond network and more around the success of products of these organisations followed by factors like the winner (or top 3) gets it all in most of these domains.

For eyeball traffic APNIC IPv6 stats for India (source here) as well as Hurricane Electric’s IPv6 progress report (source here) give us some numbers:

  1. Very few fixed-line operators are offering IPv6 but on the mobile side – a large number of mobile networks are offering IPv6. Jio was on IPv6 since launch and as traffic increased, Airtel as well as Vodafone + IDEA also significantly increased their deployment. On fixed line, it’s just Jio + ACT broadband with any sizable IPv6 footprint. BSNL + Airtel have virtually no deployment. There might be some other network in the list but it’s off the radar.
  2. There are a lot more end users on IPv6 than despite the small number of networks offering it because of the large mobile user base. On Jio 80%+ user base, on Airtel, it’s 45%, on Vodafone & IDEA (merged company but still separate ASNs) it’s close to 50%. That’s the number of users who are connecting over IPv6 when given option of IPv4 and IPv6 as tested by APNIC. That number is huge!
  3. Around 98.5% of TLDs (top-level domain names like .com, .net etc) are IPv6 enabled. For .com & .net domains, only 7% of the domains have an AAAA record (compared to ones having an A record). Most of the numbers are much lower if we look at the content side of IPv6 (ignoring the traffic volume).
  4. If we look at the content players with IPv6 and include the traffic volume numbers then it’s way higher. It is estimated that globally somewhere between 20-30 top ASNs carry 90%+ traffic and almost all of those top 20 are IPv6 enabled.

What do all these numbers actually mean?

  1. If you are an eyeball network in India and you deploy IPv6, you can expect way over 70-80% traffic (by volume) on IPv6.
  2. If you are a content network/datacenter in India and application is targetting to home fixed-line / enterprise network, expect a rather low amount of IPv6 traffic but would be rapidly increasing as more fixed-line networks deploy.
  3. If you are a content network/datacenter in India and content hosted at your end attracts mobile traffic, you can expect way over 50%-60% of that mobile traffic over IPv6.

Some additional reasons to consider deploying IPv6

  1. In India, ISPs need to maintain carrier-grade NAT logs of the translations. If one is doing dual-stack, a large part of traffic will flow over IPv6 saving on those logging requirements.
  2. For ISPs, it will save you from significant strain on CGNAT device.
  3. For content network/webmaster/datacenter – IPv6 will help in delivering your traffic outside of (often) congested CGNAT paths.

Happy IPv6ing! 🙂

VoWifi experience on Jio

Since last week of Nov 2019, I am having serious issues with Airtel at my home. Somehow 4G signal SNR is very poor and most of the calls just fail on that. Airtel support just mentioned that they are putting a new site in my area in Jan 2020 but fail to explain why suddenly it went so bad. I can imagine that support team staff does not have visibility to network in real-time and likely it would be an issue with the 4G antenna on one or more towers. 2G signal was good but latency was extremely high to connect call plus calls still failed regardless (maybe due to high strain on 2G).

So by the end of December, I just gave up and gave the request for porting to Jio. Yesterday my number started on Jio and around 24 hours later I got access to VoWifi which is quite nice. Both Airtel & Jio are rolling our VoWifi but for Airtel, many users have reported it for being locked on Airtel fixed line only.

What is VoWifi?

Well, it’s just native offloading of voice calls over the fixed-line network and is extremely useful for both network operators as well as end-users. Native IP equipment is cheap and it’s way easy to extend cell coverage at home via Wifi instead of proprietary inbuilding solutions. Plus landline was good for quality but form factor and usability was pain. Now VoWifi kind of merges the fixed-line and cell phones and we get best of both worlds.

I think many people confused BSNL Wings with VoWifi. VoWifi is seamless offloading of calls natively while BSNL Wings offered a separate number, an app to run and a separate billing account to maintain with the operator. BSNL Wings was a bad product idea and really awful execution.

Coming to Jio VoWifi, some misc observations:

  1. It’s working for me on the non-Jio fixed-line connection in Haryana circle. I have IAXN (GEPON FTTH) and Siti broadband (DOCSIS 3.0) at home running in active/backup configuration for high availability.
  2. The device has an IPsec tunnel with 49.44.59.XXX. I see isakmp-nat-keep-alive packets every 20 seconds when I do tcpdump on the router.
  3. On my cell phone (which is an Apple iOS device) I see a tunnel is opened on IPSEC1 port. IPSEC2 & IPSEC3 are there for VoLTE.
    IPSEC1 has a link-local IPv6 and an IPv6 from 2405:205:3000::/36 range. The IPv6 on all three IPSEC tunnels is the same as of pdp_ip1 (Cellular data port). I guess that’s probably how they are handing the handovers between VoWifi and VoLTE.
  4. The IPv6 on pdp_ip0 for cellular data is from a different range which again is being announced in the global table as 2409:4051::/36. I wonder why Jio is using publically routable pool for VoLTE and VoWifi. In case of Airtel it a non-routed address space and routes are not announced in the global routing table.
  5. In my test VoWifi to VoLTE was reasonably OK. I tested by shutting off wifi on the cell phone as well as unplugging the cable from wifi AP to test. In both cases call went silent for 1-2 seconds and resumed over VoLTE. It did not come back on VoWifi once Wifi was back live.
  6. Latency from both connections to other endpoint (the router before the IPSEC endpoint) is around 60ms. Either the endpoint is somewhere far off or (more likely) it’s a case of not-so-good routing between Airtel (upstream of my ISP) and Jio.
  7. There’s a quite noticeable improvement in connection time. For IVR based numbers it’s close to 2-3 seconds. Which is a great improvement for someone like me who was on 2G non-VoLTE calls for December!

How to check interfaces and routing table on your phone?

Well use HE.NET Network App on Android or Apple iPhone and you will be able to check that!

That’s about it. Back to the world of routing. 🙂
