be part of the full mesh.

I would assume that R3 also has two BGP routes to R2, but does not have an
entry in the routing table either.
Step 1 of the BGP decision process is to ignore routes with an

If you have access to CCO, you can take the output of "sh stack"
("enable" first to get all pertinent data), and run it through the stack
decoder. It will hopefully come up with the cause and associated bug ids.
Research the specified bug ids, and cisco may document a known fix.
There are several ways you can affect how traffic enters your autonomous
system. The most popular is prepending your autonomous system number 1 or
more times on your outbound announcements. Though, some find that
prepending is not granular enough.
You can go a step further, and prepend
