[j-nsp] Get a route not to be installed in one router in an OSPFarea?

According to OSPF spec, everyone in an area must agree on and have the same
database.  So you aren't allowed to prevent an LSA from going to one device
inside an area (through an ABR you can).

But you can use an import policy on the router you don't want to have things
in order to prevent the route going from the OSPF database into the routing
table.  So it'll still exist in OSPF it just won't be used.

Hi,
I have a couple of M-series routers running OSPF in a single area. Is there
an easy way to configure the net so that one of them not recieves/installs a
particular route distributed in OSPF?

I.e. I would like router X not to install the route 192.168.0.0/24 in the
routing table. This router X is only connected to one of the other routers
on interface Y.

Best Regards
/// Fredrik
