Re: aggregation tool wanted

[Jared Mauch <jared () puck nether net>]

        I once started a project that would do this, which would
allow realtime aggregation by speaking ebgp to a router.  I've not had
time to play with it too much, but it does bring up a bgp session and
receive routes properly.

        If I ever finish it, I'll run it and put up a telnet/http interface
to it.

        I would also check out Tony Bates CIDR report, as you can do
interesting things with that data, it will tell you if you can
aggregatte better.
