VOIP issues/Cisco TAC offline?
by Cat Okita 12 Nov '06

12 Nov '06

I've been getting either voicemail or nothing via the network down option for Cisco TAC from about 01:45EST Nov 12th onwards (it's about 03:30 now); taking the 'existing service order' option ends up in a fast busy after putting in the number. Calling the US 408-* or the EMEA numbers directly has the same result. I seem to recall that Cisco's gone pure VOIP, and I'm wondering if that might be the source of the issue - and if that's the case, if anybody would care to comment/speculate about ways to avoid this type of issue in other deployments. cheers! ========================================================================== "A cat spends her life conflicted between a deep, passionate and profound desire for fish and an equally deep, passionate and profound desire to avoid getting wet.

odd hijack
by Josh Karlin 10 Nov '06

10 Nov '06

I recently brought up a prefix hijack that the NANOG community solved, the AS had accidentally started announcing their bogon list. Here is one that is somewhat the opposite, the AS announced a significant portion of IANA allocated space. Note, they are large blocks and as such probably did not cause much damage because most networks announce more specifics. My question to the community is, what kind of misconfiguration could cause this set of prefixes to be announced? I asked the AS responsible, but have not had a response. If you would like more information on the hijack, please see the Internet Alert Registry forums at http://cs.unm.edu/~karlinjf/IAR/ Following are the AS's announced prefixes during the ~10 minute hijack from earlier today: 11.0.0.0/8 12.0.0.0/7 121.0.0.0/8 122.0.0.0/7 124.0.0.0/7 126.0.0.0/8 128.0.0.0/3 15.0.0.0/8 151.99.190.0/24 16.0.0.0/6 160.0.0.0/5 168.0.0.0/6 172.0.0.0/8 188.0.0.0/8 189.0.0.0/8 190.0.0.0/8 191.0.0.0/8 192.0.0.0/8 193.0.0.0/8 194.0.0.0/7 196.0.0.0/8 198.0.0.0/8 199.0.0.0/8 20.0.0.0/7 200.0.0.0/8 201.0.0.0/8 202.0.0.0/7 204.0.0.0/7 206.0.0.0/7 208.0.0.0/8 209.0.0.0/8 210.0.0.0/7 210.170.0.0/18 212.0.0.0/7 214.0.0.0/7 216.0.0.0/8 217.0.0.0/8 218.0.0.0/7 22.0.0.0/8 220.0.0.0/7 222.0.0.0/8 24.0.0.0/8 25.0.0.0/8 26.0.0.0/8 28.0.0.0/7 30.0.0.0/8 32.0.0.0/6 32.1.21.168/32 38.0.0.0/8 40.0.0.0/8 41.0.0.0/8 43.0.0.0/8 44.0.0.0/6 48.0.0.0/6 56.0.0.0/7 58.0.0.0/8 59.0.0.0/8 6.0.0.0/8 60.0.0.0/7 62.0.0.0/8 63.0.0.0/8 64.0.0.0/5 72.0.0.0/7 74.0.0.0/7 76.0.0.0/8 77.0.0.0/8 78.0.0.0/7 8.0.0.0/7 80.0.0.0/7 82.0.0.0/8 82.143.0.0/18 82.143.0.0/20 82.143.0.0/21 82.143.10.0/23 82.143.12.0/24 82.143.16.0/20 82.143.32.0/19 82.143.32.0/24 82.143.33.0/25 82.143.8.0/23 83.0.0.0/8 84.0.0.0/6 88.0.0.0/7 90.0.0.0/8 91.0.0.0/8 96.0.0.0/6 Thanks, Josh

You should also create a bogons list for your BGP routes which you accept from your upstream. Block all RFC1918 space and unassigned public addresses too. Just keep on top of it when new allocations are put into use. We see all kinds of crazy things which people try to announce (and successfully too - up to our borders anyway.) -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin

RE: Verizon PSTN continued
by Wallace Keith 10 Nov '06

10 Nov '06

Working with 2 other carriers on a similar issue, response I rec'd was congestion due to automated political dialers. Not sure if I believe that or not... -Keith -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of David Hubbard Sent: Tuesday, November 07, 2006 12:32 PM To: nanog(a)merit.edu Subject: Verizon PSTN continued The thread yesterday didn't seem to get into much detail; I'm wondering if anyone knows more about what is going on with Verizon? Our PSTN service with XO seems to be affected again by what XO claims is a Verizon problem but they wouldn't elaborate on why they feel that to be the case; I was just amazed to even get someone on the phone at XO since normally they are unreachable. I am inclined to partially believe them since I've found other numbers that I know to be with other carriers that are not working. XO claimed this was at least a regional issue of Verizon's that is affecting multiple carriers. David
