Re: Route table growth and hardware limits...talk to the filter
Thus spake "Jon Lewis" <[email protected]>
The trouble is, it turns out there are a number of networks where CIDR isn't spoken. They get their IP space from their RIR, break it up into /24s, and announce those /24s (the ones they're using anyway) into BGP as /24s with no covering CIDR.
IMHO, such networks are broken and they should be filtered. If people doing this found themselves unable to reach the significant fraction of the Net (or certain key sites), they would add the covering route even if they were hoping people would accept their incompetent/TE /24s.
