Unfortunately, this was basically the first thing I tried, and it
doesn't work. Anything I did with such a policy only exported *more*
into IS-IS, not less. This is probably related to the IS-IS default
export policy, e.g.
http://www.juniper.net/techpubs/software/junos/junos72/swconfig72-policy/html/policy-overview-framework3.html
which says "Reject everything. (The protocol uses flooding to announce
local routes and any learned routes.)"
So I guess I'm looking for a way to influence the flooding.
