I do think I was misunderstood here.
1. Classless addressing is the worldwide standard no matter what
Cisco says, and should be the default approach to address assignment.
2. Summarization/aggregation/supernetting should be used WHEN POSSIBLE,
but controlled exceptions can make sense.
3. Having the full routing table available makes debugging HARDER,
not easier. The primary tools should be DOCUMENTATION, ping, and
traceroute.
4. Redistribution isn't always a temporary fix. While it should be
regarded
as such when converting from a less capable (e.g., IGRP) to a more
capable (e.g., OSPF, EIGRP) routing protocol, there are perfectly
valid
reasons to do redistribution of static routes, to selectively
redistribute
into RIP in the specific case where it is being used to help hosts
find
specific gateways, and, WHEN YOU KNOW EXACTLY WHAT YOU
ARE DOING, in and out of BGP.
