If you do not give a child matches, the child is less likely to start the
fire then if you give child matches. If you do not explain to the child that
it should try playing with fire before he/she realizes what kind of effect
that fire may have, the child is less likely to try it.

Link state protocols should die. 

Cisco has tons of bugs in OSFP + CEF and OSPF + dCEF implementations. They
are called "strange CEF things". Should me a router vendor and I will show
you that it has broken routing protocols.

There is absolutely nothing wrong with a concept of communism, none the less
it is better not to try implementing it.

We are not talking about concepts here - we are talking aboung engineering
robust routers.
