Outage recovery
by Randy Barrett 01 May '97

01 May '97

Hi folks: I was struck lurking on the list at how all you network types worked together to solve Friday's outage. While some may worry the Net is vulnerable, I think it probably proved its resilience, on the whole. Anyone care to comment, public or private replies welcome. Thanks Randy Barrett Senior Writer Inter@ctive Week http://www.zdnet.com/intweek Phone: 703-938-2087 Fax: 703-938-2088

I do agree; it was only because of people working together (albeit with maybe a little yelling) that it was fixed as fast as it was. It could have been a _LOT_ worse.

When there is a lot of churn, some of the EBGP peergroup members might not receive the withdrawn message. This will happen only if the EBGP neighbors have tons of update queued (ie unless the EBGP neighbors are receiving thousands of prefixes, this bug will not be seen.). Thus it is most likely to affect people using EBGP peergroups within the confederation. If you are not using EBGP peergroup, it will not have any problem. I already have the fix and should be available soon. The bugid is CSCdj08110. --ravi > ------- End of Forwarded Message >

AGIS: ???
by Stephen Balbach 28 Apr '97

28 Apr '97

AGIS has been offline on the East Coast since about Tuesday. Im not sure of the scope, but it seems pretty catastrophic [for AGIS customers]. Checking www.agis.net/states.htm then pick any East Coast state and unless the ISP is multi-homed, all traceroutes stop at Pennsauken [cut to protect the innocent] 9 f1-0.pennsauken1.agis.net (192.157.69.19) 129 ms 185 ms 114 ms 10 * * * 11 * *^C * 12 ^C I estimate at least 25 smaller single-homed ISP's have been entirely cut off for days. AGIS NOC says it has MAE EAST problems (coinciding with the transition to the Ascend GRF Monday morning?). AGIS has been stateing that this is caused by SPAM attacks but I suspect thier upgrade to an OC-3 ATM backbone plus the GRF is at the heart. Anyone have any more info? .stb

[ savvis folks asking which versions have the "bug"] we just found that 11.1.7ca1 contains the "bug" but we haven't gotten an exact description of what the bug is. in general terms, it's only been described as: "a bgp router can be slow in withdrawing prefixes even though they've been withdrawn from the originator(s)." doesn't say much, does it? :) they're working on a fix. i'm afraid i dont' know which other versions have the same problem though. we only asked about a particular version we run. -brett
