I seem to recall a massive routing failure in October which was caused by BGP getting imported to a major ISPs IGP... The core ${VENDOR 1}routers were able to handle the influx of routes, but the edge ${VENDOR 2} routers could not handle the influx - so the failure didn't exactly cascade, but did more of a ripple. However, the reloading of all of the edge devices increased the BGP instability. -David Barak -fully RFC 1925 compliant- __________________________________________________ Do you Yahoo!? Yahoo!
