This is wisdom... I can only add that the whole "EIGRP v OSPF" debate, and EIGRP's alleged scaling problems are mostly related to the lack of clueful design from the onset.
The things you have to do to get good scaling from EIGRP are the very same things you do by default when designing for OSPF (ie: Good Hierarchical IP Design, effective summarization, etc). When designing an OSPF network, things are things that *must* be taken into account at the beginning. More often than not, in an EIGRP network, these things have been overlooked because EIGRP does not strictly require them in a small to medium-ish environment, and as a result, when the environment grows larger, these poor design choices manifest themselves as instability, and people tend to blame the protocol, rather than themselves. Had they followed good design principles from the beginning, they would most likely be satisfied by EIGRP's stability and scalability. That said, a good understanding of OSPF will make a person a better engineer/designer in the EIGRP arena as well. Good practice applies equally to the two protocols. ----- Original Message ----- From: "Howard C.
