Yep we saw the same, every customer with old IOS had their sessions die to us at the same time... That always makes for an interesting time when watching the NMS system... We are seeing a much more sane path now: agg2-sea-A>show ip bgp 94.125.216.0/21 BGP routing table entry for 94.125.216.0/21, version 25944571 Paths: (1 available, best #1) Multipath: eBGP Advertised to update-groups: 2 3 5 6 7 8 9 3561 3356 29113 47868 208.76.153.96 (metric 5102) from 208.76.153.96 (208.76.153.96) Origin IGP, metric 0, localpref 50, valid, internal, best Community: 11404:1000 11404:1040 agg2-sea-A> John van Oppen Spectrum Networks LLC Direct: 206.973.8302 Main: 206.973.8300 Website: http://spectrumnetworks.us -----Original Message----- From: Andy Davidson [mailto:andy@nosignal.org] Sent: Monday, February 16, 2009 9:10 AM To: John van Oppen Cc: Matt Liotta; nanog@nanog.org Subject: Re: anyone else seeing very long AS paths? Hi, Yep, we see them too. Nasty because there are lots of networks flapping as the long as-paths are tickling old bug CSCdr54230, so even networks not affected by the bug will be getting lots of extra updates. Anyone with contacts at 47868 ? Any upstreams onlist that want to bin them ? Andy
