Given that we've had an incident like this twice in the past month, I'm seriously concerned about the network operations of "top-tier" providers.
I'll say we certainly try hard to mitigate these issues. It's hard because while platitudes on this list don't cause IOS devices to not send a full routing table by default (for example). I would like to see others participate in the dialog with vendors so we don't seem to be quite an outlier with "wow, you have really large configs". The vendors haven't quite kept pace with the increase in density proportional to the number of configuration lines and it sure feels like we are the only people pushing them to improve. This combined with the number of devices that are doing kinky routing to 'optmize' a network make it more likely that something will cause damage. rfc1925 2.(9)a applies. - Jared -- Jared Mauch | pgp key available via finger from jared () puck nether net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
