Do not forward LSA interests to routers not in the same network. Multiple networks should not interfere with each other. Currently, if two routers are working on different network prefixes, e.g. `/ndn/` and `/ccn`, LSAs distributed will leak into the other network, and cause interruptions. * On a single computer, multiple NLSR processes could run simultaneously without interfering with each other. * LSAs distributed for one network would not clutter other networks.
