I'm guessing most people already know this. I should have known it.
I just figured it out after years of using this equipment. I'm thinking
of how many times I've done redistribution with access lists wondering
if I used the correct access list.
Duh! All I had to do is `show ip route list x` against a full routing
table.
No mystery at all.
Below is where I was checking a summary address; then below that, an
even list.
