In return, would Covad please consider performing some meaningful form of
route
aggregation or other measures to reduce the amount of noise that is being
passed across the global routing tables that originates from Covad?
http://www.cidr-report.org/cgi-bin/as-report?as=AS18566&view=4637
suggests that Covad could withdraw some 483 BGP routing table entries,
reducing the total number of entires originated by Covad from 490
to an equivalent set of 8 aggregate routes.
Perhaps use of NO EXPORT when announcing the more specifics to your
upstream transit providers would be a globally helpful action to consider.

Geoff Huston

All,
It has recently come to our attention that many Internet routers are still
filtering out IP addresses in the 69.0.0.0/8 range. If YOU are still
filtering this block in your router, please modify your filters accordingly.
Thank You
