[AusNOG] International link issue

Thu Feb 23 17:29:14 EST 2012

It doesn't happen very often, otherwise people who don't have filters in place wouldn't be able to get away not having them for very long. That's not to say they shouldn't be filtering or at least limiting the number of prefixes they accept before dropping BGP sessions from a customer to prevent or minise the impacts of these sorts of accidents.

It's easy to describe for all the media types watching..
(And I'm not sure why its not being put out there in Laymans terms).

>From the routes seen at various points, and reported on the WAIX mailing list earlier..

Dodo told Telstra that Dodo was the rest of the Internet.

Telstra Believed Dodo.

Telstra entire system tried to use DODO as their ISP instead of everyone else Telstra is connected to.

Needless to say this didn't work, the pipes got Jammed.

Telstra should have filtered the announcement from Dodo, but didn't.

Filtering is in place as a form of control (which is used instead of trust).

Filtering obviously wasn't in place, or didn't work, so anything that Dodo told Telstra about where to find the Internet, Telstra believed.

This happens quite often, I've heard of this happening on peering exchanges within Australia, too. Just never at an organizational level as big as Telstra.

Over and Out.

+1 on the PIPE issues.  I've got our PIPE link disabled at the moment until this settles down.

Optus seems OK for Domestic and Intl so far.
