Re: Route table growth and hardware limits...talk to the filter

There's a couple of feature requests open at Cisco that would do this.
Rodney Dunn (at Cisco) pushed quite hard for these but couldn't get any
traction. As he's previously pointed out it would have if people would
vote for them (attach a case to).
Maybe this is a dumb question, but why isn't there a BGP option to just
filter more specific routes that have the same AS path as the larger
aggregate? This would allow the networks that announce more specifics for
traffic engineering to still accomplish that, while throwing away the
garbage from someone else that decides to announce their /19 as 33 routes
for no apparent reason. Sure, this would fail if a network decided to
only announce /24's for example without a larger aggregate, but how many
networks are really doing that?
