Date: Wed, 1 Mar 2006 23:46:22 +0000 From: [email protected] Let's look at IPv4 options:when/if a shim6 proof of concept is built, 0x83 0x04 0x04 0x?? 0x?? 0x?? 0x?? usually doesn't make it very far. Try % traceroute -n -g ip.of.some.router and.of.the.destination from a few endpoints. This is for a reason, yes? Or maybe people just blindly copy "no ip soure-route" from the Cymru secure IOS template... and maybe Rob was just having fun when he labelled it "noxious". :-) It's not shim6, but it's something of an analog that's here today. Perhaps shim6's "intelligent" decisions would assuage transit's concerns about endpoints selecting the links. I doubt it. (Would anyone turn on LSRR if your downstreams spoke multihop eBGP with other endpoints, then used that information to select the source route?) Something along the lines of "no ip shim6" makes these threads moot. ;-) Eddy -- Everquick Internet - http://www.everquick.net/ A division of Brotsman & Dreger, Inc. - http://www.brotsman.com/ Bandwidth, consulting, e-commerce, hosting, and network building Phone: +1 785 865 5885 Lawrence and [inter]national Phone: +1 316 794 8922 Wichita ________________________________________________________________________ DO NOT send mail to the following addresses: [email protected] -*- [email protected] -*- [email protected] Sending mail to spambait addresses is a great way to get blocked.
