as he sees 2 routes, only one of which contains 9198, he could just filter
incoming routes which contain 9198 if that's the party sending prefixes
and then not relaying the traffic towards them (which kinda breaks things ;)
alternatively just drop the 12997 neighbor sesssion alltogether, if a
significant number of routes they give you go over 9198, and 9198 is the
one breaking things.
