It can be challenging to advise DDoS mitigation subscribers on their RPKI-ROA needs
by Steven Wallace 18 Oct '24

18 Oct '24

DDoS mitigation services, particularly those that dynamically announce more specific routes during an attack, add complexity when advising customers on creating their RPKI-ROAs. Smaller organizations, often served by networks that provide DDoS mitigation on their behalf, might be unaware of these services or lack an understanding of how traffic is rerouted. In some cases, you can identify customers of DDoS mitigation services by looking at as-sets published by these providers or by investigating related IRR objects for the IP addresses. However, this approach isn’t reliable. Currently, there’s no established best practice for helping organizations determine the correct ROAs to create. This can lead to confusion, especially when DDoS mitigation is involved. ARIN plans to implement a check in their hosted RPKI interface that will help validate proposed ROAs against the current global routing table. While this feature will be useful, there is a risk that it could give DDoS mitigation customers a false sense of security. They might create ROAs that inadvertently block their DDoS scrubbing service from functioning properly. I’d like to engage with stakeholders in this space to explore opportunities for improvement. Any suggestions or input on this topic would be greatly appreciated. thanks, steven Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu

arista full tables recommendation
by Alex Buie 15 Oct '24

15 Oct '24

Hi all, We're an arista shop (primarily 7050qx-32s, 7050tx, and 7060cx right now) and wanted to get some input on recommendations for "real routers" that can better handle full internet tables. As it is right now we do some creative import filtering to import and inject a handful of routes we care about due to limited fib space and otherwise just use a default received from our carriers, with any particular transit carrier being the "primary" at a given time and using pingcheck <https://github.com/arista-eosext/PingCheck> to influence that decision. We'd like to move towards consuming full tables (or at the very least, customer routes) from each of our ISPs - would be grateful for any pointers or recommendations in arista models or family of devices that would be good core/peering routers, especially other than the latest generation. We'd be landing 10g optics from the carriers currently and peering to the downstream switches at 40G or 100G. (frequently we are in the used equipment space for our acquisitions so previous generation or two or three tends to land us in a pretty good spot). thanks in advance for any advice you can provide! Alex

CGNAT growing pains
by Jon Lewis 13 Oct '24

13 Oct '24

We started rolling out CGNAT about 6 months ago. It was smooth sailing for the first few months, but we eventually did run into a number of issues. Our customer base is primarily FTTH with "dynamic" IP assignment via DHCP. Since connections are always-on, customer ONTs/routers get an IP assigned, and then when the lease is renewed, they request a new lease for the existing IP, and, in general, that request is granted. This gives customers the mistaken impression they have a static IP. So, my impression, from working with some customers who've needed to be moved from CGNAT back to public IP is that customers who are doing port-forwarding don't even bother with dynamic DNS. They just know they can connect to their IP as they've never seen it change. We do offer/sell static IP, but pre-CGNAT, it was strictly for business customers. i.e. A residential customer could only get static IP service by converting their account to a business account. That may change in the near future. One issue we didn't foresee has been IP Geo issues. i.e. We all knew that streaming services like Netflix use IP Geo to determine what content should be made available, but that's, AFAIK, limited by country or region. What we didn't anticipate is services like Hulu Live TV doing IP Geo down to the city level to determine which local channels are a subscriber's local channels. We're using Juniper MX gear and SPC3 cards for our CGNAT routers, each one having a single large external pool. Since we serve most of FL, one external pool can't IP Geo correctly for customers as far apart as Miami and Jacksonville hitting the same CGNAT router. We don't currently have an acceptable solution to this other than moving impacted customers off CGNAT. One of the great unknowns (at least for us) with CGNAT was what our PBA settings should be. i.e. How large each port-block should be, and how many port-blocks to allow per customer. We started with 256x4. It seemed to work. We eventually noticed that we were logging port-block exceeded errors. This is one aspect where Juniper's CGNAT support is lacking. There's a counter for these errors, and it's available via SNMP, but there's no way to attribute the errors to subscriber IPs. We're polling the mib and graphing it, so we know it's a continuing issue and can see when it's incrementing faster/slower, but Junos provides no means for determining if "PBEs" are all being caused by a single customer, a handful of customers, etc. We have a JTAC case open on this. As a quick & hopeful fix, we both increased the port-block size and block limit. That helped, but didn't stop the errors. It also cut our CGNAT ratio by more than half (64:1 -> 28:1), if we stay at this ratio, we'll need much larger external pools than originally anticipated. Tuning these settings is kind of painful as JTAC strongly recommends bouncing the CGNAT service anytime CGNAT related config changes are made. This means briefly breaking Internet access for all CGNAT'd customers. For the PBEs, JTAC's suggestions so far have been to shorten some of the timeouts in the config and to keep doing what we're doing, which is a cron job that essentially does a "show services nat source port-block", parses the output looking for subscriber IPs that have used up the ports in several of their port-blocks, then does a "show services sessions source-prefix ..." and logs all of this. This at least gives us snapshots of "who's a heavy user right now" and lets us look at how they were using all their ports. i.e. was it bittorent, are they compromised and scanning the internet for more systems to compromise, is it legit looking traffic - just lots of it, etc.? The latest CGNAT issue is a customer with a Palo Alto Networks firewall connected to our network and several of their employees are our FTTH customers. On their PANW firewall, they're doing IP Geo based filtering, limiting access to internal servers to "US IPs". Since we only CGNAT traffic to the external Internet, their on-net employees hit the firewall from their 100.64/10 IPs and get blocked. I suggested they whitelist 100.64/10, saying we block traffic from 100.64/10 from entering our network via peering and transit, so they can be assured anything from 100.64/10 came from inside our network / our customers. They say the firewall won't let them whitelist 100.64.0.0/10, giving an error that it's invalid IP space. I know we're not the first to implement CGNAT, so I'm curious if others have run into these sorts of issues, or others we haven't run into yet, and if so, how you solved them. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Blue Stream Fiber, Sr. Neteng | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________

Frustration with increasing information demands from Network Vendors
by chiel 12 Oct '24

12 Oct '24

Hi, I have an handful of Juniper devices (mx204 / QFX5100). I recently bought a new QFX5110 switch I want to update to a newer software release. My account on the Juniper website seems to be disabled and therefor I send an email to customer care. They replied with a form that I have to fill in. A couple of of the questions are "/$ Revenue Range/", "/# of Sales Reps/", "/# of Office Locations/". "/Details of potential opportunities in progress (also Provide)/". I only filled in the form with my own details (name, email address, etc..) and said I refused to give information about the other questions. Juniper (customer care) replied with "/Please note we need these details to reinstate the account. We can not proceed if the form is incomplete/. " I really really really find it disgusting that companies have no problem asking for this kind of information!! Its not only Juniper but also other major brands. I just bought a single switch and I can't update it without sharing all this information. I'm I do only one that feels this strongly about this?
