by Jeffrey Negro 03 Dec '09

03 Dec '09

There appears to be a Comcast outage in central NJ, more specifically in the South Brunswick area. Comcast appears to be aware of the outage as per the message I got when I called them. Anyone hear any details on the issue, or an ETA for repair yet? Jeffrey

Re: Consumer Grade - IPV6 Enabled Router Firewalls.

A list of CPEs, routers, firewalls and other hardware and software are at http://www.ipv6-to-standard.org/ César Olvera -----Original Message----- From: Wade Peacock [mailto:wade.peacock@sunwave.net] Sent: Wednesday, December 02, 2009 5:16 PM To: nanog(a)nanog.org Subject: Consumer Grade - IPV6 Enabled Router Firewalls. We had a discussion today about IPv6 today. During our open thinking the topic of client equipment came up. We all commented that we have not seen any consumer grade IPv6 enable internet gateways (routers/firewalls), a kin to the ever popular Linksys 54G series, DLinks , SMCs or Netgears. Does anyone have any leads to information about such products (In production or planned production)? We are thinking that most vendors are going to wait until Ma and Pa home user are screaming for them.

FTTH Active vs Passive
by Luke Marrott 03 Dec '09

03 Dec '09

I'm wondering what everyones thoughts are in regards to FTTH using Active Ethernet or Passive. I work for a FTTH Provider that has done Active Ethernet on a few networks so I'm always biased in discussions, but I don't know anyone with experience in PON. I've read before that almost all PON technology is proprietary, locking you into a specific hardware vendor. However I think this is changing or has already changed, opening PON up for interoperability. Can anyone confirm this? Thanks in advance. :Luke Marrott

DNStop is a real good tool for what it does. It's an exceptionally useful tool and probably at the top of my list for deciphering DoS attacks targetting or amplifying against DNS resolvers. But for RTT and timeouts, errr not so good. Sorry for the top post. Stupid Blackberry...

STP Visualization
by Brian Feeny 30 Nov '09

30 Nov '09

Can anyone recommend a good tool for spanning tree visualization? I am needing to get a good visual depiction of forwarding for many vlans, across 4 core switches. Two of them are CatOS, 2 are IOS, root is different for many of the vlans, lots of port costing in place, in other words it would take a while by hand. Thanks, Brian

Anyone have a clueful mail admin contact for tpg.com.au? The usual attempts result in completely clueless and unhelpful responses, going round in circles with no progress. -Dan

Re: Fiber Cut in Italy
by Hank Nussbacher 30 Nov '09

30 Nov '09

The first cable cut occurred at 13:43 GMT close to Vernegues-France involving a group of six cables, damaged by an excavator, interrupting the service on the segment Marseille-Lyon. The second cable cut occurred at 14:21 GMT on a highway near to Milano/Bersaglio, about 530km away, interrupting the service on the segment Milano-Zurich. Service was restored at 1:40 GMT the next day. It just shows that protected fiber rings do have an enemy - and his name is Murphy. -Hank >TI Sparkle just confirmed they are having a fault. > >Email from Telecom Italia Sparkle - Seabone NOC: > >Dear >We have a big fault ( fiber cut) in france 2 cuts and one in milan. > >We are working to solve it asap. > >Regards > > >- Telecom Italia Sparkle SpA >Customer Assistance/Assurance I° t Se at bone Network Operations Center Via >M.

Finding asymmetric path
by ML 29 Nov '09

29 Nov '09

I'm reasonable certain a customer of ours who is using one of our netblocks is using a different reverse path to reach us. How might I figure out who is allowing them to source traffic from IPs that belong to us?
