Re: maximum ipv4 bgp prefix length of /24 ?

About 60% of the table is /24 routes.
Just going to /25 will probably double the table size.

or maybe just add 60%, not 100%.  and it would take time.

agree it would be quite painful.  would rather not go there.  sad to
say, i suspect some degree of lengthening is inevitable.  we have
ourselves to blame; but blame does not move packets.
