www.worldnet.att.net routing problems

Does anyone have information why ATT's Worldnet portal is being routed through Splitrock, UIUC and NCSA? It seems to have pretty much taken the Worldnet site off the net. > nslookup www.worldnet.att.net Server: localhost Address: 127.0.0.1 Non-authoritative answer: Name: www.worldnet.att.net Addresses: 204.127.43.37, 204.127.12.39 route-views.oregon-ix.net>show ip bgp 204.127.12.39 BGP routing table entry for 204.127.0.0/20, version 4137919 Paths: (1 available, best #1) Advertised to non peer-group peers: 64.166.72.140 1224 38 10514 7018 5731, (aggregated by 5731 204.127.128.251) 141.142.12.1 from 141.142.12.1 (141.142.12.1) Origin IGP, localpref 100, valid, external, atomic-aggregate, best route-views.oregon-ix.net>

But RFCs 2182 and 2870 offer good guidance. (Some of 2870 is root zone-specific, but most of it would apply to a ccTLD server.) --Steve Bellovin, http://www.research.att.com/~smb (me) http://www.wilyhacker.com ("Firewalls" book)

Well, aren't fire extinguishers supposed to explode anyway upon high temperature? Rick Cheung NPI IT Wan Team, CCNP -----Original Message----- From: Christopher J.

Though many people either miss the point or don't care, RFC 1918 is also BCP 5. Last I checked, BCP stood for "Best Current Practice." So you've got a BCP document saying the addresses listed in RFC 1918 should not be present on the public network. So yes, filtering is required by RFC 1918, and so use of the private IP address blocks does break Path MTU discovery. Some folks find the private address space specified in RFC 1918 convenient, but ignore the stipulations on use contained in the same document. ----------------------------------------------------------------- Daniel Senie dts(a)senie.com Amaranth Networks Inc. http://www.amaranth.com

Cisco quality
by Ralph Doncaster 07 Jun '02

07 Jun '02

For those saying Cisco is so great, it's still fucked up pretty bad. IOS 12.1 and later doesn't allow an MTU > 1460 on L2TP, while 12.0.7(T) works fine with a 1492 MTU that my PPPoE customers expect. Every rev I've tried from 12.0 and up has problems with CEF when using ISL VLAN sub-interfaces, and without CEF, mac-accounting is screwed up. Now if they charged 1/5th of what they do, I'd say you're getting reasonable value for your dollar... Ralph Doncaster principal, IStop.com div. of Doncaster Consulting Inc.

LINX-accredited certs
by Andy Harding 07 Jun '02

07 Jun '02

at the risk of re-igniting the formal- vs. cert-educated thread, I wonder whether anyone has seen the new (to me at least) LINX-accredited certs? http://www.linx.org/training/index.thtml http://www.s-nt.co.uk/ looks (to me) like an interesting concept - ie ISP-industry-oriented rather than vendor-specific - although I'm not sure it would get offered outside the UK it may be vendor-independant, but I'd put good money on the lab kit being vendor-c 2500s ;-) -andy
