Frustrating loss of connectivity...FOLLOWUP

I'd like to take a moment to quickly publicly thank Darryl, Kevin and Roy from Level 3 that jumped on this issue right away tearing through logs and historicals and then watching the suspect link and providing me the debugging information. In addition, I also was contacted by Todd from Covad and he provided some suggestions and information we'll be able to use to properly open a case and get it referred in the correct directions. THANKS GUYS! - Robert

It *is* the same box, as has been repeatedly pointed out. Maybe you could expand on the BGP scanner problems - we haven't seen them all the time we've been running 6500 native with full routes (about 1.5 years now).

When the signal is placed on the wire, it is very analog. the digital signal is modulated onto the wire and demodulated off of it and the box that connects to the phone line at each end is properly and fairly commonly called a DSL modem. If the path was entirely digital, it would be a CODEC (CODer/DECoder). It is a modem. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.

... And seeing as that all most switches are is a glorified multiple port bridge, feel free to go to your 7500 and make it a switch by placing "bridge-group 1" on every port, and if you want to get really crazy and make it a L3 switch, go all out and put in a "bridge 1 route ip". :-) -----Original Message----- From: Michel Py [mailto:michel@arneill-py.sacramento.ca.us] Sent: Monday, October 13, 2003 7:02 PM To: Richard A Steenbergen; Mikael Abrahamsson Cc: nanog(a)merit.edu Subject: RE: Extreme BlackDiamond > Richard A Steenbergen wrote: > So a 7500 with a fast cache is a L3 switch? :) Of course.

Banishment? >You should make sure you know who the perp is before making such >pronouncements (or maybe it doesn't matter). Not really. It's the list owner who should know who the perp is before taking action. In any case, it's quite easy to figure out who dragged the dispute onto the list by checking the incoming messages. In this case one person sent a private email and the perp sent a profane reply copied to the list. Clearcut case.

Juniper M7i, M10i and the US DREN's IPV6 project
by Eric Kuhnke 13 Oct '03

13 Oct '03

Here are some interesting tidbits found recently... The US DoD will be using a Juniper "M7i" for their ipv6 testbed: https://spot.hpcmo.hpc.mil/hpc/docs/Htdocs/DOC-MIL/DREN/CONFERENCE/2003/200… Mention of the M7i and M10i in this document: http://216.239.41.104/search?q=cache:CHexJWF9Db0J:www.ietf.org/IESG/Impleme… From the PDF, regarding DREN implemention of ipv6: No great incentive for DREN sites to implement IPv6 no near term win additional effort and complexity, generally not funded Can't deploy in a safe and secure manner Existing DREN intrusion detection (IDS) architecture incompatible with maturity of products in use Juniper port mirror lacks IPv6 support Anybody know what a the new M7i and M10i routers are? Specs, price estimates, release dates, etc?

That would make a great April 1 RFC! Michel.
