[c-nsp] advertising a route not in IGP (summary)

[Jeff Bacon]

And the winner is... ip eigrp summary-address leak-map. 

I spent all this time focusing on the BGP side (I've been crash-coursing
BGP lately), not realizing that the summary-address command had gained
new features in the 10 years since I last used it. :) *sigh*

In the process, I also found a stupidity in my overall setup (I kept
thinking it was a summary address but it was actually a static route),
so now I have an opportunity to change the entire setup and make it
nicely elegant. Win all around. Weee! 

Though I will want to understand bgp inject-map as well.. so much to
learn.

Thanks folks
