AH or ESP
by Glen Kent 22 May '09

22 May '09

Hi, It is well known in the community that AH is NAT unfriendly while ESP cannot be filtered, and most firewalls would not let such packets pass. I am NOT interested in encrypting the data, but i do want origination authentication (Integrity Protection). Do folks in such cases use AH or ESP-NULL, given that both have some issues? Thanks, Glen

Pseudowire Problem
by Shivlu Jain 22 May '09

22 May '09

I have seen a weird behaviour in case of pseudo wire termination, it keeps on polling the destination ip even if the interface mapped to pseudo wire is down. Is it the normal behaviour? -- Thanks & Regards shivlu jain http://shivlu.blogspot.com/

Global pricing disparity -> Somali piracy
by Martin Hannigan 22 May '09

22 May '09

FYI, I thought this was interesting reading for the workaholics among us as we head into the holiday weekend in the United States. I'd also like to follow it with an (hopefully) interesting question. http://www.circleid.com/posts/20090520_bandwidth_buyers_price_differences_g… The costs of wholesale bandwidth are significantly disparate by region, duh, but this article demonstrates how disparate. I was also recently discussing why some of these costs are disparate with a colleague in the African region and he had an interesting question that I thought would be operational enough to ask here. Are any African or Middle East costs being influenced by the Somali piracy problem? Is the deployment of Eassy being impacted by the piracy issue? The cable ships are sitting ducks for pirate attacks during lay and repair operations. There's one cable lay operation being guarded by the French Navy, likely an Alcatel operation. I'm interested to hear from anyone with direct knowledge (offline, I'll summarize back if it's worth it, maybe even a lightning talk for Philly?) on the impact. I suspect that it's possible that it could add cost to maintenance agreements with any security caveats, but since most cable operations taking place now were negotiated before the problem heightened, perhaps not. I'd like to know if you know. Best, Martin Hannigan -- Martin Hannigan martin(a)theicelandguy.com p: +16178216079 Power, Network, and Costs Consulting for Iceland Datacenters and Occupants

in urgent need of router w/T3 interface
by Adam Goodman 22 May '09

22 May '09

I have an urgent need for a router to replace the one that crocked last night. If you have a router to sell or lend please contact me off list It could be the following or equivalent of a Cisco 7000 with the following interfaces: 1x T3 clear channel (like a PA-T3) 1x FastEthernet (Alternatively I can also use a wanPMC-C1T3 card with a PCI adapter.) Thank you, -Adam Adam Goodman E: adam(a)wispring.com C: 801.971.1856

Google BGP Cisco... Should give you 90% of this. ------Original Message------ From: ty chan To: nanog(a)nanog.org Subject: Local Peering and Transit - BGP multihoming Sent: May 22, 2009 2:23 AM Dear all, In my lab, i manage two ASN (100,200). ASN100 has one transit to ASN300 and local peering to ASN500. ASN200 has one transit to ASN400. ASN100 do private peering to ASN200. Some policies are required as below: 1. ASN100 customer can only use ASN300 for transit 2. ASN200 customer can only use ASN400 for transit. 3. Local traffic will stay local between ASN100,ASN200 and ASN500. 4. ASN100 and ASN200 are backup each other only if either upstreams is down. How to configure BGP to meet the above policies? I am using Cisco devise. best regards, chanty Sent from my BlackBerry device on the Rogers Wireless Network
