Re: BGP route tracking.
> Anybody watching the bgp routing table.. I see about 5,000 less routes than > usual. Anybody know a good pointer.. Okay, here are a couple quick screenshots of what we're looking at tonight. First, a plot that shows the routing table size shrinkage since the onset of the blackout at 16:13:07 +/- EDT, across a group of routers. http://gradus.renesys.com/aug2003/blackout1-rtsize.gif Second, a wider-angle 3D plot of prefix withdrawal rates over the last week, reported by various peers (one line per). http://gradus.renesys.com/aug2003/aug7-aug14-withdrawals.gif The blackout is the big event at the right hand edge (#3). Note the sustained high rates of route withdrawal that have been the norm since the onset of MSBlast. Unlike typical single-cause events (like the one marked #1), MSBlast scanning has caused prefix withdrawal rates to gently "lift off" into a noiser mode across the board, lasting for days (so far). > (im just getting bored waiting for us to run out of fuel) Ouch .. ---------- James Cowie Renesys Corporation [email protected]
