[nsp] Direction of manual summarization

[Cheung, Rick]

	Thanks to everyone who replied on the 5 9's Infrastructure question
posted recently.

	I have a question on manual summarization. In practice, with EIGRP
in a hub/spoke network, do we typically summarize addresses towards the
core, or summarize it to the spokes? The intent is to limit the EIGRP
queries from rippling to the edge routers, as we're trying to work around
CSCdr91621 on our edge 4232 L3s. 

	I believe, however, best practices state to localize queries, and
not propagate them to the core. 



Thanks,
Rick Cheung
