Help with broken routing in MTL (AS577 174 11647) Bell, Cogent, Me
by mike tancsa 24 Jun '22

24 Jun '22

We noticed random traffic originating from AS577 stopped getting to our ASN via Cogent in Montreal at around 00:24 this morning. Based on the pattern I am guessing a broken next hop on one leg of a larger link ? e.g. IP traffic leaving AS577 towards IP addresses in one of my /19s will 100% work for certain IPs and 100% fail for others all within that same /19. e.g. from 142.112.93.72 (an IP originating in AS577) to one of the IPs below in my 64.7.128.0/19 64.7.134.1 100% fail 64.7.134.2 100% pass 64.7.134.3 fail 64.7.134.4 fail 64.7.134.5 fail 64.7.134.6 fail 64.7.134.7 100% pass 64.7.134.8 100% fail 64.7.134.9 fail 64.7.134.10 pass Its just packets towards my ASN that are failing. Packets TO 577 via 174 all work fine. Traceroutes good and bad all look like this % traceroute -s 142.112.93.72 -q1 -I 64.7.134.2 traceroute to 64.7.134.2 (64.7.134.2) from 142.112.93.72, 64 hops max, 48 byte packets 1 lns5-ottawa23_lo0.net.bell.ca (64.230.11.188) 10.507 ms 2 64.230.98.68 (64.230.98.68) 17.539 ms 3 tcore4-montreal02_1-9-0-0.net.bell.ca (64.230.79.127) 18.150 ms 4 cr02-mtrlpq02ho6_bundle-ether1.net.bell.ca (142.124.127.251) 13.787 ms 5 bx1-montrealgz_et-0-0-5.net.bell.ca (64.230.26.135) 12.237 ms * 6 ** 7 be2089.ccr21.ymq01.atlas.cogentco.com (154.54.45.113) 13.337 ms 8 be3259.ccr31.yyz02.atlas.cogentco.com (154.54.41.205) 17.969 ms 9 sentex.demarc.cogentco.com (38.104.158.78) 17.126 ms 10 agas-core1-em0.sentex.ca (67.43.129.251) 39.960 ms 11 agas-lns1c-c.sentex.ca (64.7.129.19) 32.171 ms 12 orbiting.anysphere.com (64.7.134.2) 49.336 ms % traceroute -s 142.112.93.72 -q1 -I 64.7.134.1 traceroute to 64.7.134.1 (64.7.134.1) from 142.112.93.72, 64 hops max, 48 byte packets 1 lns5-ottawa23_lo0.net.bell.ca (64.230.11.188) 10.229 ms 2 64.230.98.66 (64.230.98.66) 13.346 ms 3 tcore3-montreal02_hu2-4-0-2.net.bell.ca (64.230.78.252) 12.660 ms 4 cr01-mtrlpq02ho5_bundle-ether1.net.bell.ca (142.124.127.233) 12.423 ms 5 bx1-montrealgz_et-0-0-1.net.bell.ca (64.230.26.133) 12.225 ms *6 ** 7 * 8 * 9 * 10 * 11 * Not sure if hop 6 is a Bell device or Cogent device. I have a ticket open with Cogent, but they dont see any issues in their network. I am not a direct customer of Bell, so I cant open a ticket with them. Was hoping someone from AS577 would see this and take a look. ---Mike

Good Monday Morning Everyone. Quick Question: What is everyone's favorite software for running a looking glass. A friend asked me this over the weekend - and while there are others available on the internet to use - it would be helpful for them to run one within their own network.

Carsten, No, it’s more like 50,000 furnace guys who show up several times a day to rattle doorknobs, attempt to push slim Jim’s into window latches, hack your garage door opener, sneak into your back garden, and fly drones around your home to see what valuables you might have. Yes, some of them are altruistic, but some are self-righteous officious boobs, and the vast majority are career criminals that will rob your house, drain your retirement account, and kill your family with a spoofed SWAT raid. -mel beckman > On Jun 20, 2022, at 4:20 AM, Carsten Bormann <cabo(a)tzi.org> wrote: > On 2022-06-20, at 04:18, Mel Beckman <mel(a)beckman.org> wrote: >> >> When researchers, or whoever, claim their scanning an altruistic service, I ask them if they would mind someone coming to their home and trying to open all the doors and windows every night. > > Well, it is more like the guy who comes once a year and checks that your central heating is not going to blow up. > > (Disclaimer: I have supervised students who designed and executed benign mass-scans of the IPv4 Internet in order to validate hypotheses about market penetration of certain security updates, and I definitely would do that again if there is a good reason to perform such a scan.) > > Grüße, Carsten
