Can I do this in EVPN? (Multihome to more different CEs)
by Simon Lockhart 10 Feb '23

10 Feb '23

All, I have a bit of a networking design challenge, and I thing EVPN is the right answer, but despite spending the last week reading loads of resources about it, I can't quite get my head around one aspect. I'm trying to genericise the design a bit here, but what I've got is... I have multiple layer two broadcast domains that I need to link together over a layer 3 network. The broadcast domains consist of multiple switches carrying multiple vlans spanning multiple locations (think of it like a customer campus network). I need to interconnect with each broadcast domain in two different locations. (so two PEs to two CEs), and link it back to a datacentre in another city. In the simple case, using EVPN, I see that I can run active-standby multihoming, configuring one ESI for the customer campus network. If one of my PEs fails, or one of the customer CEs fails, then EVPN will fail over to the other link. However, the failure scenario I need to deal with is if a layer two link fails between two locations within the customer campus, the two halves of the now split broadcast domain still need to be able to communicate with the datacentre (but do not need to be able to communicate with each other). Every example I can see for EVPN shows multihoming to a single CE, and I can't find anywhere an example which deals with a "split" ES. Is there a solution to this problem? Many thanks in advance, Simon

(IETF I-D): Implications of IPv6 Addressing on Security Operations (Fwd: New Version Notification for draft-gont-opsec-ipv6-addressing-00.txt)
by Fernando Gont 09 Feb '23

09 Feb '23

Hi, All, Recently, I happened to participate in an IPv6 deployment meeting with some large content provider, and said meeting included a discussion about how to mitigate some attacks using block-lists. These folks argued that they ban offending IPv6 addresses as /128s, following IPv4 practices. So it seemed to me that some of the implications arising from the increased IPv6 address space were non-obvious to them. -- that has been the motivation for the publication of this document. * TXT: https://www.ietf.org/archive/id/draft-gont-opsec-ipv6-addressing-00.txt * HTML: https://www.ietf.org/archive/id/draft-gont-opsec-ipv6-addressing-00.html Comments welcome! P.S.: The document is targeted at the IETF opsec wg (https://www.ietf.org/mailman/listinfo/opsec) but I'll be happy to discuss it on this mailing-list, off-list, or at the opsec wg mailing-list... Thanks! Regards, Fernando -------- Forwarded Message -------- Subject: New Version Notification for draft-gont-opsec-ipv6-addressing-00.txt Date: Thu, 02 Feb 2023 19:48:40 -0800 From: internet-drafts(a)ietf.org To: Fernando Gont <fgont(a)si6networks.com>, Guillermo Gont <ggont(a)si6networks.com> A new version of I-D, draft-gont-opsec-ipv6-addressing-00.txt has been successfully submitted by Fernando Gont and posted to the IETF repository.

This document discusses such implications, and sheds some light on how existing security operations techniques and procedures might need to be modified accommodate the increased IPv6 address availability.

Yondoo provided router, has "password" as admin pw, won't let us change it
by typhoon.notice_0a＠icloud.com 09 Feb '23

09 Feb '23

Hi, Long time lurker, first time poster. Sorry in advance if this is the wrong forum for something like this. My mom's ISP (Yondoo) seems to be providing DOCSIS 3.1 CPE (Customer Premises Equipment) with a built-in router, without providing the ability to change the admin password from "password" on it. Their customer service rep said that this is not only WAI, but also wanted to charge her $50 to have a tech come out and change it. Which is obviously less than ideal. That aside, this seems like a pretty egregious security standard which, from my understanding, can have fairly dire security implications... e.g., DNS server settings can be pointed at whatever someone wants here. My mom is elderly and had already fallen victim to a call center scammer a couple years ago. They briefly took control over her laptop before she called for backup. So I'm just a little concerned that we have no control over changing this router's admin password — from “password” — in a pinch, without waiting for a truck roll && shelling out $50. I've sent her a DOCSIS 3.1 modem that doesn't have a router built-in, in hopes that they'll let us bring our own. She does have Google Wifi, but we can't even put their router into bridge mode. So she would be double NATed and have no control over changing the admin password on the first router. Anyone have any experience with Yondoo? I've tried reaching out to them on multiple fronts, but have yet to hear back from them on this. A tech is scheduled to come out tomorrow, so the plan is to beg (bribe?) them to let us use our own modem and then take it from there. Thanks, Todd

Apparently iCloud’s hide my email implementation can only be used with one recipient, so here was my reply to Josh (apologies to him for the spam), for posterity: Hi, Thanks for your reply. Double NAT tends to break things like ZeroTier. But even if that wasn’t a problem for us, I think the more pressing concern here is that the default admin password for the router is “password”, and you can’t change it without a tech coming out to change it for you, and shelling out $50. Who knows how many residential routers are in their fleet that are “password” protected; seems like a disaster waiting to happen. The model was an Evolution Digital EVO3000GW — thankfully they were able to swap it out with a non-router modem that I had sent to her over the weekend, but not without making a few phone calls, first. It didn’t seem like they could provision the new modem remotely. If anyone has a more security-focused forum they could recommend for a post like this, I’ll be happy to take my inquiry elsewhere.

Lima, OH Spectrum/Charter Severe Node/Hop Latency Issues
by Austin Ayers 08 Feb '23

08 Feb '23

Hello all, One of my NetOps engineers resides in Lima, Ohio and they are receiving terrible bufferbloat, packet loss, and random disconnects. I have been pinging 24.33.160.213 (Lima, OH Spectrum/Chart Node) and it's rejecting a ton of packets. This has been going on for weeks. Node having problems: lag-1.limaohid01h.netops.charter.com NOC seems like they don't care, same with OSP in the field. There is no reason why this hop (#13) should have up to 613ms ping times. Thank you, Austin [cid:d929237e-d932-4060-9dbb-f4b99b12afa4]
