[Olsr-users] Multi-hop OLSR

[Song Gao]

It's possible to use block certain node at link layer by using
iptables with --mac option. Check this page out:
http://www.cyberciti.biz/tips/iptables-mac-address-filtering.html

By blocking certain nodes from one node based on mac address, OLSRd
control messages are also blocked, as a result, OLSRd would consider
the blocked nodes not reachable, and build multi-hop routing tables.

Kind regards,
