As it was explained to me, the main difference is that you can have $lots of

resource-intensive and as such OSPF doesn't get too happy after $a_lot_less
prefixes. Those numbers can be debated as you like, but I think if you wer

FWIW Quagga works fine as a looking glass if you don't mind the telnet

admittedly less elegant.
