Yes, we are aware of this and started last week to implement some further aggregation. Our upstream providers have to get their prefix filters updated before we can go ahead with the routing change. That process is almost complete.

Either tomorrow or early next week we should be cutting our routes by approx. 100 prefixes.

Have a great day!!!

AS271 has been lately seen to be sending out too many prefixes not based on CIDR boundries, thereby increasing the global router table size:

ASnum NetsNow NetsCIDR NetGain % Gain Description AS271 280 132 148 52.9% University of British Columbia

See http://www.mcvax.org/~jhma/routing/ and http://www.employees.org:80/~tbates/cidr-report.html for further details.

I hope you can take the time to add the appropriate BGP filters so that the we all do not suffer from global router table bloat.

Thanks, Hank
